This ebike will become VERY popular Neeko. Great video. It's the cheapest 52v kilowatt battery full suspension ebike with the M620. Beating Frey Biktrix and Luna in terms of price performance power and capability. No modifications like building a diy battery is required. Looking forward to the E22 vs E55. But I think I know which bike will ultimately win👍🏾
Hmmm!! I never thought about it like that. You could be right Ruban. Dengfu are usually consistent with their price👍🏿
Indeed if I could get one just a bit bigger I'd be tempted myself.
(Though actually I will build a tadpole if I can afford it.)
This bike looks really good Love it 👍
Great stuff!
Now he just needs a HV kit to go along with it, hook him up!
Lol. Don't worry. The hv kit will come in handy...once the M630 arrives🤫
Great info! It's possible to remove the battery even without the key if you first unscrew the top bracket which holds the battery from the top (the two screws above battery from the outside) and then wiggle it for a bit.
Great looking ebike and very good walk around of the bike love the details ✌👍
You answered a lot of my questions Neeko. Thanks buddy.
Very informative video. Thanks for your time and effort.
Hi buddy, I bumped into you today on the canal, I was on my one wheel. Just subscribed 👍
I got confirmation from Dengfu. The E82 is out but currently only size 17" frame sadly. They said they might do 19" and other sizes in the future.
Now I'm waiting for them to open the EU warehouse and Bafang to release the new version of the 750w m560. Hoping those happens soon so I can build my bike before summer.
Great video Nikko & lots of usefull info. I recently built one for my ridding buddy & its a beast . if you mount the rear shock the opposite way round with the small can on one side this frees up the bottle area & allows for easy adjustments to the shock settings. also if you need to add a range extender battery this helps with the space.Keep the content coming & hopefully more people will build the bike they want & not what the manufactures want to sell.
👍🏿
Hearing you talk about the headset cable routing has only confirmed what i thought from the beginning. NOT FOR ME!!!. The E55 looks cool and hearing you talk about the 1000wh 52v battery which doesn't trip out when riding sounds good. But that headset cable routing cant be overlooked for diy frameset builders. I did like what you said at the end of the video and I agree👊🏾
I appreciate your apprehension. You wouldn't be the first person to be put off the cable headset routing method. I'll gladly say, this won't be the only DIY frameset which uses headset cable routing👍🏿
I'm not sure I like (or even see any advantage to?) headset cable routing, but when you look at some of the narrow channels some frames have...
The E55 looks fairly spacious by comparison?
I just received my E55. Something is wrong with the headset. The steering is stiff, making the bike unrideable. I have tried setting the headset, but it doesn't help. Either it is too loose and clunks or the steering is bound making a grinding sound. There is no reason for this to occur from the factory. Any suggestions?
Hi there,
I'd be more than happy to assist if you're encountering issues with the headset.
Use the links in the description to either the Dengfu Frame Ebike Owners Group on Facebook or Dengfu E55 & E56 thread on EMTB Forums and create a post taking pictures of your headset and cable routing. From there, I should be able to assist.
Failing that, feel free to contact me directly through Facebook, Instagram etc (links to my social media platforms on my bio page).
Look forward to hearing from you👍🏿
I took it to a bike shop and they said that the reason that I could not get the head space to adjust properly is that the lower bearing was installed upside down. @@neekodevinchi
Pretty cool bike🤙 29er's are the future!
Agreed. The bike picks up speed very quickly and can truck through some gnarly terrain without losing composure and inspiring confidence.
Thanks for the comment👍🏿
I don't know why anyone would choose something other than the Bafang M620 for a home build. The thing about choosing the highest available motor unit is that... if you don't want to go fast, you just don't use a 'full power' setting. But if and when you do want more power, you have that headroom and heat capacity. With a lower power model... you can only twist the throttle so much until it just doesn't physically twist anymore.
The M620 has always been one of my favourite motors. Even though it doesn't get talked about, technically it's one of the longest running frame specific ebike motors of all time. I'm sure you've also heard about the Bafang M630 motor. Keep a watchful eye my friend👍🏿
At lower wattages (particularly once battery voltage drops) the motors with larger rotors like the m620 are often much less efficient than smaller, lighter (& cheaper) motors. Big people & people wanting tons of power for things like a cargo bike, will want big motors like the m620, but lighter riders who don't need much assist can get more miles per Watt-hour from some of the smaller motors.
_Personally,_ I'd like to get a 52V 14s6p 18650 pack even if we keep our m620's controller set up for 48V nominal: If the display will allow it, the motor will perform better if Voltage never drops below 50. The m620 _hates_ low voltage; its efficiency absolutely plummets!
Another great video mate. Lots of useful information. Alas, I’ve said this before and I’ll say this again, you need to take this bike off the tame single tracks that you ride and put it in the true environment in which it was meant. You have both Kinver, Cannock Chase and The Wrekin right on your doorstep. You can’t leave it to Rob Rides to give this bike the shakedown it deserves.
Cheers John. Yeah, I'll need to test the bike outside my local nearby trails👍🏿
@@neekodevinchi I’ll believe that when I see it but not before. FYI: I’ve just invested in a bike carrier, if you know what I mean?
😄
that is sweet
I would ride one of those, the bike looks cool, one issue I have with many of these commercial e-bikes though is they don't provide a mechanism to install another battery to increase the bikes range.
I'm glad you've said that. Rumour has it, that a auxiliary battery (range extender) is being developed for the E55. Once I've got credible information, I'll happily spread the word👍🏿
A range test video with that kilowatt battery would be nice neeko👍🏽
I can do that👍🏿
Hello! Great video, because of it I really want to build this bike starting with just only frame, I guess maybe in two years it will be ready lol. Anyway can you post your all bike parts?
Hi there, rest assured I'll elaborate on the specific build & components of the E55 in the upcoming content (especially the comparison between the E22)👍🏿
Hello friend,it looks good no prob 😅😊 and fast
It is fast😁👍🏿
First off...well done and nice detail. Thanks for taking the time to put this up! Second...why did they go bigger and heavier? It seems the market is going in the opposite direction but Dengfu and Watt Wagons seem to be going larger.
I can't speak on behalf of Watt Wagon. But Dengfu will be releasing their super light/mid assist emtb soon. This will be called the Dengfu E69 using the Bafang M820. The E55 (in my opinion), was never built and/or marketed as a lightweight bike. Having said that, its not much heavier than the E22👍🏿
A decent battery weighs over 12lbs; meanwhile we have people on carbon rims lauding the use of hub shifters with >8% drag.
Weight is a big drag (pun intended) when climbing long hills, but other than that it's not as big a deal as many other inefficiencies that remain quite prevalent on flats or even downhill.
Certainly it affects the feel of the bike & I'm _not_ saying weight doesn't matter, but by the time I put all my gear on my manual 29er it's over 34 pounds; I'll generally take better over lighter, when it comes down to that, & spending to shave ounces would often be better spent adding cells.
Nice Neeko, let me say that you CAN drown an M620 but it takes full immersion for a period of time. Sad and expensive day it was. Not enough difference to get me off my Z1 overall but a good choice for those that are new to the concept. I also highly recommend the 52v motor. I was able to run my LUNA original M620 on 52v oddly enough but the replacement they sent me for the drowned motor would not operate on 52v, or even 48v for that matter so they took it back and I got the 52v UART version from GBK. Looks like you are having a damp summer, all sunny here on the coast of Oregon! Best, Mabman
Cheers Mabman👍🏿 Year, our summer season is a bit dismal😅
Here in Colorado we're getting enough cloudy/rainy days to avoid going over 100°F/37.5°C _and I'm loving it!_
What uart????
It refers to the communication protocol (its difficult to explain the differences through a mere message). But fear not. I'll explain the differences in an upcoming video. So keep a watchful eye👍🏿
@@david029014 Neeko definitely has more hands-on knowledge of CANBus & UART used in ebikes than I do, but I'll try to explain a bit based on what I know from automobiles & embedded systems, without indulging in technical tangents:
The differences most obvious to an end user, would be:
1. CANBus systems send signals along a *pair* of conductive wires that loop through each component, with *each component responding only to certain signals,* whereas UART systems route wires to\from *each component individually,* so UART will often end up using more strands of wire per route than CANBus (although this is apparently still not many, on an ebike).
For manufacturers, fewer strands of wire can add up to savings on materials, & for builders, it *could potentially* mean a few less wires to run. (Though at present, it's still the same number of *bundles* of wire, but I'm sure Neeko would agree that it's easier to route a bundle containing fewer strands!)
For end users, it's not a very visible difference until you need (someone) to deal with an issue... (see point 2)
2. CANBus signals are coded to each device, so while a UART motor-controller will accept any battery\display\etc adhering to protocol, a CANBus motor-controller is capable of rejecting a battery or display that doesn't match ID codes keyed by the manufacturer. Likewise, a CANBus motor-controller's settings can more readily be locked behind a passcode or behind a proprietary app requiring authorization over the Internet, so that only personnel authorized by the manufacturer will be able to replace any electronic modules or to adjust the motor-controller's settings to accommodate a different bike part\configuration.
Purely off the top of my head, thus far, John Deere, BMW, GM, Tesla, Lockheed Martin, Apple, Bosch, & now Bafang, have all earned harsh criticism for selling devices with firmware locked to prevent adjustment & aftermarket parts installation by "unauthorized third parties", specifically excluding the end-user *and* any service technicians whom the OEM hasn't specifically authorized.
Specifically to the Bafang m620's internally mounted motor-controllers, *the UART versions* permitted a lot of very detailed reconfiguration by individual builders or rebuilders, via a (cheap & common) UART-serial-port-to-USB adapter & any app used for UART communication (including the old Bafang Config Tool app for Windows). Bafang's *CANBus versions* of the internally mounted m620 motor-controller, initially offered *no* service or advanced configuration options via the early iterations of their 'BESST' app, because even the very few people allowed that access, were presented only a couple crudely implemented sliders of just two settings, for adjustment; no true fine-tuning was possible.
*_Now,_* I've heard that the BESST tool *can* provide particular authorized personnel with access to additional settings & config menus, but I can't actually vouch for that as I haven't had reason to look into it yet. (Our m620 & its original UART controller are working great, after some vital calibrations.)
On a *personal* level, with the gritty (& potentially quite deadly), hard fought, ongoing legal & market-backed battle for Right-to-Repair, I can't even consider getting myself _(or others)_ vendor-locked into a CANBus-locked Bafang (or Bosch) ecosystem. (We're already looking at Framework laptops for these very same reasons...) I can't condone or in any way recommend *choosing* CANBus systems that are service-restricted in such a way. Too many large & previously influential companies over the decades have left clients high & dry with devices designed to prevent service in the absence of OEM support. (Cisco, Google, & Ring, to name just a few more offenders.)
From the perspective of a reseller who's changing the lineup of ebike systems they sell every few years at least, it's hard to argue that a motor system they've no real intention of rebuilding or modifying, needs to be openly serviceable.
From the perspective of a highly technical, detail-oriented builder (such as Mike at High Voltage ebikes), a CANBus controller that doesn't allow enough config, gets swapped out with a controller that does. (Check out their work putting an ASI BAC-855 motor-controller on an m620 motor.)
So, a lot comes down to the people buying these motors: Will the market reject CANBus lockouts widely enough to cause Bafang to resume offering 3rd-party serviceable motor systems (or go under), or will locked-down proprietary systems carve out so much market share that bike builders & consumers alike, feel cornered into acceptance?
CANBus offers technical advantages over UART, as a wired communication protocol for vehicles. Its only significant _downside_ is that it has been used to undermine Right-to-Repair & 3rd party service opportunities; were it not for that factor, CANBus is a pretty great tech for simplifying otherwise complex wiring harnesses.
Hello Neeko First of all thank you for all your research and documentation of the Bafang and Dengfu brands.
I had finally bit the bullet on purchasing the m620 + carbon frame when I noticed the new m560 with 140Nm and weighing 3.4kg less than the m620.
Weight to power ratio this seems like the superior engine. Will you be covering this one as well? Or will you skip this in favor of the upcoming m630?
hi Vince, yes. The plan is to compare the new M560 (750w 140NM) to the M620. This is where my E10 will come in handy. In addition, I will be covering the M630 as well. My intention will be cover the M820 in due course which is a lighter 75NM motor, so keep a watchful eye. more Bafang and Dengfu content to come👍🏿
Allo Neeko, this winter I will order E55 frame, and built my own ebike, can you make a video which parts you orders and installed,
I can do that👍🏿
Thanks for this, good info, is there no uk stockist of parts? I did a very brief review of a different model, I must admit it was a nice ride. I will get one ordered, great value.
Hi there.
First things first, HUGE FAN👊🏿.
Currently, Dengfu are looking into implementing a dedicated avenue specific to UK/EU customers. At present, Carbon Cycles via eBay.uk is fulfilling a lot of orders. But the frameset/complete bike is still being shipped from China. Dengfu have explained that there plan is to get a dedicated warehouse, native and convenient for shipping/handling/warranty enquiries (like Winice for the US riders). Once I've got more Intel, I'll spread the word.
However, I have found more and more uk merchants who are selling Bafang motors and equipment. Titan Pro have definitely earned my respect (link in the description).
But I'll keep my ears to the ground and share any and all information I learn. Keep up your amazing vids and thanks for your comment👍🏿
Hi, Thank you, glad you like the channel. I'm at the minute binge watching yours, great content and really well explained, messaged Mia at Dengfu and ordered an E55 Frame and kit, bit of a side exciting project to look forward to. thanks for the info on the Dengfu future plans, keep up the good work. Dave, YBM@@neekodevinchi
Hey mate, can do a video on cable routing etc on this model? Only thing im truely unsure about!
I can do that👍🏿
I'm interested in this!
Links are in the description to Dengfu, Carbon Cycles and Winice. In addition, feed free to join our community on Facebook or on EMTB Forums👍🏿
you could just replace the bottom headset with a 56/30, then you could run a straight 1 1/8 steerer?
Good point👍🏿
I could pick that battery lock and have it out in 5 seconds lol. Anyway, I'm really considering buying one of these bikes but I'm 6'5 with longass legs, do they make an XL size that I might be able to stand on the pedals without killing my knees?
Dengfu have hinted that they "might" introduce an XL size, subject to the popularity of the E55. But I suspect that the large frame might feel cramped for yourself at 6foot 5inches.
But fear not, I will be covering further DIY emtb frameset which would be to your size. So keep a watchful eye👍🏿
@Neeko which frame gives more clearance from the ground to the motor? E55 or E22?
And how much does bike weigh with that heavy battery?
Hi there. in terms of ground clearance (BB Height), the E55 has more ground clearance. As for weight, technically the E55 would be the heavier bike compared to the E22. although, I can only compare the weight difference between my E22 with either the 840wh (48v17.5amp) & 720wh battery (52v14amp) vs the E55's 1040wh 52v21amp battery). I presently don't have the 960wh (48v20amp) battery. Although, I do have a 670wh (48v14amp) battery which (technically) can be retrofitted to the E55 making it lighter👍🏿
@@neekodevinchi you're awesome. Thank you
What brand dropper post and cable kit did you install -Thx!
Apologies for the delay. One Up 180 dropper with Bontrager Line Lever. Initially, a 210 One Up dropper was inserted fully. But needed a service. Either way, a 210 or 180 one up dropper can be ran in the large e55 frame👍🏿
Thanks for the overview - do you think you could measure the q factor?
Sincere apologies for the delay. The Q-factor is 187mm. Bare in mind, I'm running the Raceface Aeffect 165mm cranks (not the stock Bafang 170mm cranks]. The Q-factor 'may' vary depending on this👍🏿
@@neekodevinchi No need to apologize friend, you just did me a solid - thanks!
Hi Neeko. I hear that you're the guy to speak too about Bafang Motors and ebikes. I'm looking for an ebike which isn't heavy but uses the bafang motors as they are cheaper compared to Bosch but just as strong. I've heard that the M620 and M510 are considered Bafang's best motors. But is it possible for a bafang ebike with one of these motors to weigh less than 20kg/44pounds? Would love to pick your brains and thanks for the good videos👍🏻
hi there. Many thanks for your enquiry and apologies for the delay. As far as I'm aware, there aren't 'many' ebikes which use either the M510 or M620 which weigh around or less than 20kg when fully built. _ Maybe a hardtail like the Dengfu E14_ . That's not to say that it's impossible. but the system weight of either the M510 and/or M620 makes it difficult. However, I will be covering very soon the *Bafang M820* which is one of Bafang's lighter ebike motors which has *75NM of torque* and weighs in at 2.3kg. Meaning that the frames can be built up lighter than either the E10 with the M510 or E22 with the M620. Keep a watchful eye but I'll keep my eyes peeled on any examples of light ebikes which use the M510 or M620👍🏿
@@neekodevinchi Thank you. Just Subscribed. Whats the price of the M820?
Looks a bit of a weapon that bike! I'd have thought a 160mm Zeb might have been a better fit for a bike like that?
True. A 38mm stanchion fork would be the best option. Sadly, trying to find one with a 51mm offset is proving difficult. But fingers crossed, I'll bite the bullet and buy one in due course. (I'm gonna need one, as my E22 uses a Fox38 now😄)👍🏿
I know this will vary with suspension sizing & adjustment (& I'm hoping you usually run a_lot_ more pressure than we saw today?), but how would you compare the Bottom-Bracket height between the E22 & the E55 _when you're standing on the pedals?_
Our XL sized Frey AM1000 v5, has a crazy long chainstay length (thankfully zero retention issues so far) & a relatively _high_ BB height, _when there's no weight on the bike,_ but due to the lonnnng suspension layout it sags relatively low once I'm on it.
I'm interested to know what BB height your bikes ride at, once tuned & loaded with your rider weight!?
What's up Prophet Zarquon. I assume you're referring to the anti-squat and anti-rise between the E22 & E55. in short, the anti squat of the E55 is greater than the E22. Whereas the anti-rise of the E55 is slightly lower than the E22, due to the longer chainstay length. The axle path is the same between the two. But that shouldn't be surprising, as the suspension layout, brake mount to rear axle position and the yoke driver are the same. The BB height of the E22 is lower than the E55 (if you build them both with 170mm forks). This coincides with a suggestion I made a while back concerning using shorter cranks on the E22 (no longer than 165mm cranks). The reason for the difference of BB drop, is simply because of motor orientation.
Hope this answers your question but I'll go into detail in upcoming content👍🏿
@neekodevinchi I was actually referring to the BB drop that occurs when placing a rider's weight on the bike even without rotational pedal force: BB height measurements seem to be taken at full suspension height when no one's on the bike, but for a full-suspension bike that's not the actual height when seated or standing on pedals. (That's why downhill bikes have so much higher BB than cross-country trail bikes: With a lot more travel, there's more initial sag just getting on it, so a higher _initial_ BB height may drop pretty low if the suspension graduates across a longer distance under compression.)
Anti-squat
ise are designed to transfer rotational force from the pedal crank, into supporting the suspension, to reduce squat _when pedaling hard,_ but another major factor on a full-suspension bike, is that the suspension sags a bit as soon as the rider gets on, resulting in a significantly lower BB final height while we're actually on the bike, than when BB is measured without a rider.
So, while the fixed BB height for a hardtail tells us a lot of what we need to know about a frame's handling, the sag of a softail's BB height when placed under rider weight (with appropriate pressure\spring tension), makes for another vital measurement distinct from the initial unloaded BB height. _Plus_ we get to deal with torque squat & different shocks with varying travel & varying rates at which compression ramps up...
Obviously, how much air\spring is set on the rear suspension, will be the primary factor in sag between initial BB height & seated BB height, but even with the exact same rear triangle, every slightest change in mounting geometry affecting the rear triangle's travel relative to the front frame, will also affect the nominal BB sag & can therefore dramatically affect the handling of the bike.
In the case of the E22 & E55, as you pointed out, the rear triangle & suspension mounting geometry are just a bit different, so in addition to any change in torque-squat _under power,_ I'm wondering if the E55's BB sags to a noticeably different neutral riding height than the E22's, if configured with otherwise same shock type & pressure\spring levels?
(As you might imagine from its stretched out geometry, the BB on the AM1000 v5 sags _much_ lower than its initial BB height, once you put a rider on it. Even at max pressure, a RockShox Deluxe Select+ sags past 15% when _I_ get on it, but even our lightest rider notices that the AM1000's BB sags to a height lower than that of a Rocky Mountain or Specialized full-suspension bike equipped with similar length shocks.)
Given the Frey is the first full-suspension ebike I've spent more than an hour on, & any ebike I swing a leg over is likely to have at least 5 kilos of battery, I'm extremely interested to know if any of the lighter\shorter ebike frames built to a similar power level, such as your E22 & your E55, exhibit anywhere near the same level of "plushy" sag, or if they ride relatively close to their initial BB height the way a (much lighter) typical full-suspension downhill bike would!? I _like_ a low final BB height, but having a _lot_ of sag is something most road riders might feel unsettled by; it's a tradeoff for sure; I'm very curious to know your impressions, what do you think???
You raise interesting point. But the bb heights position is still determined by anti squat and anti rise.
You are correct. Depending on the orientation and placement of the rear shock, can influence these figures. However, comparing Dengfu's suspension platform to Frey's suspension platform would yield different results.
In addition, ones seated position can also influence the sag point. Which is why the E55/E56 feels more firmer. The seat tube angle is steapee compared to the E22 and E10.
I'm still playing around with the E55 and compiling my notes and data. But in answer to your question, the E22s bb height is lower. But the E55 supports more travel👍🏿
@neekodevinchi Ahh yes I remember you mentioning the steeper seat tube angle on the e55; yes that'll definitely affect the final BB height!
Gotta disagree on terminology for anti-squat, there: anti-squat specifically & only pertains to the angle of chain tension relative to the angle of rear triangle travel; when there's no chain tension there's no anti-squat in effect. That said... _I don't know of any other term_ for frame geometry designed to avoid excess sag; so maybe that's why we're at a difference of phrasing there? Or maybe I'm just a pedant. Or just wrong.
Regardless, I wonder if the extra travel possible on the e55 will also translate to just that little bit more sag than the e22, to result in a more similar final BB height between the two than initially seen when there's no rider weight on the bike.
Hi Neeko thanks for the video...ordered my E55. Curious what is the total weight of the bike? looking at bike rack options.
how u liking it
I'm thinking of buying the frame+motor+battery combo from DengFu but I'm considering if the m620 motor is wrong choice. Maybe the M560 should be the way to go. Does the motors have same mounting points and do they both fit the E55 frame?
The E55 can only support the M620 and M630 Motors. The mounting position of these motors are different to the M560/M510/M600/M500 etc.
However, Dengfu will be soon unveiling their new E47 model, which will use the M560 motor.
Keep a watchful eye on upcoming content👍🏿
@@neekodevinchi ah okey thank you! Do you have any clue when that will be? I thought they are planning to release the E82 next which is supposed to be modern version of E10? I also heard they are opening EU warehouse this year.
Bafang supposed to release the new version of the m560 soon also.. any information on these?
Does your frame have the goofy integrated kickstand cutout? I’m building one up now and it came with a kickstand. The frame has a recess in the chainstay for the kickstand. Seems like a possible weak spot for the chainstay. Not to mention the absolute ridiculousness of making an “all mountain” 150mm bike with a kickstand. Obviously won’t be using it…
Mine doesn't have kickstand provisions. But I'm aware that some E55 variants do.
Winice E55 frameset were the first I saw the kickstand mounts👍🏿
What is the standover height for this config?
Bare with me, I'll measure the stand over height and get back to you shortly👍🏿
I've been looking at these bikes but I'm 6'5 and I'm not sure a large 19" will be big enough for me. Since you have one, right there lol, what do you think? Any input would be appreciated. Thanks!
I'm 6foot 3inches. The bike fits good. But I at my height, I am on the upper limit of the E55 large frame size. Using a 50mm stem has helped as well as rolling on 29" wheels front and rear.
Being honest, I suspect a rider of 6foot 5inches might find the E55 slightly cramped. But Dengfu do acknowledge that tall riders exist. So they'll be looking to capitalise on this moving forward.
The next emtb frame which I'll be unveiling might be something you'll be interested in, Being as your a tall rider and the frame in question comes in XL👍🏿
@@neekodevinchi Bet, thanks for the reply. Give you a sub!
What cells are in the battery, 18650's or 21700's? Nice build by the way.
18650/14S5P. Their is talk of more powerful packs being developed. But this will coincide with the release of the Bafang M630 motor👍🏿
@@neekodevinchi I just spoke to Tony @ Dengfu, and he told me that they are 21700's LG cells. The battery case should be 80mm wide and 104 tall for the 21700's and 74mm wide for the 18650's . Could you tell me what yours is? Thanks.
80mm mine is measuring. I don't have the 48v battery at present. So I can't compare the two.
Hope this helps and apologies for the delay 👍🏿
look like you can fit trunnion shock, can you?
No. Metric shock (230x60, 230x62.5 or 230x65 depending on how much rear travel you want)👍🏿
You picked up the E55 with little effort. Is it lighter or Heavier than the E22
Before I answer, I'd like to run my E22 with it's 52v battery. Unfortunately (at present), I can't verify the real world weight of the E55 with the 960wh (only the 1040wh battery). But I'll declare the weight of both shortly. Having said that, I don't really notice to much static weight difference between the two when picking either of them up or popping them on the back wheel👍🏿

Мне слишком нравится этот велосипед. Но я могу помочь тебе построить его👍🏿
@@neekodevinchi подскажи пожалуйста что и где нужно заказать чтобы построить такой же велосипед
How much shipped to your door ? Ty
An E55 frameset (on average) including frame, motor, battery, display, axle, headset, wire harness, charger etc should cost no more than £1600 if you order from either Dengfu directly or one of the recommended distributors and suppliers (including shipping & tax).
If you're sensible, you may find cheaper ways of sourcing the frameset, motor, battery etc, if you buy separately from different distributors.
E.g. my frames and batteries are supplied from Dengfu. Depending on the system used per each frame, I may go elsewhere to source it. For the E55 and E22, I used Titan Pro for the M620 system. As a result, it is cheaper doing it that way.
Hopefully this answers your question. But feel free to check each link in the description to assess your options👍🏿

Hey Neeko can you give me a weight on this bike as set up in the vid.
27.8kg. However, I have swapped out the front tyre to a Butcher T9 29x2.6 which the bike ways roughly 28kg👍🏿
What is the weight of this bike ? Thank you
Currently, mine weighs 27.84kg. But it may get heavier, as I'll be swapping the lyrik for a Zeb fork in due course👍🏿
@@neekodevinchi Thank you !!
How do u afford all these builds?
Lol. I consider myself to be one of the lucky few to have Dengfu as a channel supporter👍🏿
How fast can you go on mtb ? On a normal flatt road
With the throttle, I've been able to achieve 52.2mph. It could go quicker if I changed the chainring size from 36t - 42t for example👍🏿
@@neekodevinchi - if you use throttle only, no pedaling, on flat land, it will do about 30mph top speed ?
I've been able to achieve 52.2mph in its current setup (29er fromt and rear with a 36t chainring and 52v kilowatt battery👍🏿
What drive train did you use?
*
A mixture of Shimano Deore and SLX (12spd) with a 36t chainring upfront👍🏿
@@neekodevinchi Thank you, Sir. It did look to me like it was a CS-M6100 cassette in the back, but wasn't quite sure because of the blurred angles.
Any problems with creaks or squeaks on the cassette as it picks up debris?
*
Not really. Drivetrain maintenance is mandatory. But I haven't heard any weird sounds emanating from the cassette, freehub or chain. Just make sure the gears are indexed and the chain is lubed and maintained. Obviously, heavy shifting when using the higher levels of assist should be avoided, as the probability of snapping the chain would increase. But you could use a 10spd Drivetrain if that is a concern👍🏿
How much does it cost.?
It depends. Of you're buying a complete build, subject to the components the price can vary between £2700 - £3000. If you build up the E55, the frameset (frame, motor and battery) will cost £1300 - £1500 depending on the battery pack and motor configuration👍🏿
@@neekodevinchiwhere do you get frame+motor+battery that cheap? :o I can only find the E55 on dengFus website
i prefer e10 desing , this one look terrible
Huge chunky eMTBs with the G620 is out of style these days. Dengfu bet on the wrong trend.
Not really. Dengfu aren't putting all their eggs in one basket. We do have three more emtbs to look forward to from them for 2024 (which are lighter, slender and won't use the M620/M630)👍🏿
Нико попроси Бафанг чтобы сделали на Спешилайзид Турбо Лево свой комплект : мотор-батарея-управление. Чтобы можно было выкинуть этот дибильный моторт Броз и больше его не видеть никогда!))
🤣
Я спрошу и посмотрю, что они скажут👍🏿
