    This is a wonderful, well-done video. You covered very important cautions to avoid potential serious accidents and common installation errors a first-time ebike installer would want to avoid. I do not mechanically work on bicycles, but I am handy with tools. I believe I could manage electrifying my existing bicycle from your video. Your delivery is "very" good. All of the points required roll right off your tongue; no wasted time. You covered a lot of ground in 30 minutes. I very much appreciate your common sense, thorough knowledge and your grace in sharing it with the rest of us. Thank you!!

    I recently saw one of the leading e-bike manufacturers on UA-cam dissing such refit kits. My conclusion from having long examined the possibilities is that refit is a great way to go. The flexibility in choice is enormous, and the folks at Grin have got it down pat. No, I have no affiliation with Grin.

    • @007craft
      @007craft 5 років тому +4

      e-bike conversion kits are good in theory for customization and turning your favorite bike into an ebike but they are not really ideal for most people. I recently just purchased an e-bike and was considering using a kit but once I broke down the costs there wasn't much point really. With my $600 bike, throwing a $1400 ebike kit onto it doesn't make much sense when I can buy a new brand new ebike of equivalent specs for $2000 flat out. All the labor is done for you, it looks better than a conversion and you still have your old bike!
      Now I want to get an ebike for my girlfriend and she rides a cheap bike like in this video, worth maybe $100. Theres no point in me buying a conversion kit thats 14X the cost of the bike when I can just buy her a new ebike for the same price and get a much better bike.

    • @trwashere5906
      @trwashere5906 5 років тому +4

      You're right that conversion might not always be cheaper, and I would agree with you that it may not always be sensible to put a kit on a beloved frame expecting the frame to last indefinitely. On the other hand, the same kit can be used on one frame after another, which may not be so with the e-components of a factory e-bike. As to what works best for most people, I don't feel qualified to say. Posted somewhere on the Grin website is a paper arguing the pros of going with kits. I found it a persuasive read.

    • @GrinTechnologies
      @GrinTechnologies  5 років тому +12

      For the record it's here:
      www.ebikes.ca/learn/kits-vs-turnkey.html
      We're also not saying that conversion kits are the right choice for most people, but we found that a lot of the marketing against conversion kits by turn-key bike companies (like Bosch) and shops that sell them is a little disingenuous.

    • @GrinTechnologies
      @GrinTechnologies  5 років тому +5

      3-4 hours is what we usually quote people to expect for a first time conversion which doesn't require much customization, so that is right inline and we should probably make it more clear that is what to expect. In this case we had all the pieces handy and had already done a dry run to figure out exactly how we'd be doing the cable routing and component placement, which allowed things go much faster. That dry run all told took about 3 hours!

  • @practicalguy973
    @practicalguy973 2 роки тому

    Great presentation and very informative. I was thinking if those heavy batteries provide shock to the frame to the point of loosening bolts, why not include a thin rubber or foam attached to the rack to add some shock resistance between the battery and the rack? Or maybe redesign the rack with some rubber bumpers in line with the mounting posts.

    • @GrinTechnologies
      @GrinTechnologies  2 роки тому

      Yes anything like that to dampen the shock load would help. But usually the locking rail system doesn't really lend itself to a rubbery mount so it's not that easy of a mod to perform.

    • @GrinTechnologies

      Yes, if the hub motor has just two power wires (+ and -) and a host of small d iameter signal wires then it's almost for sure got an internal controller.

  • @rider2731
    @rider2731 4 роки тому

    Hi Justine, Thank you for the presentation. It's helpful and interesting to watch. I have one question: Why is the motor an AC one? Why not DC then you don't need to convert DC to AC.

    • @GrinTechnologies
      @GrinTechnologies  4 роки тому +5

      Hi Agus, you still need a motor controller with a DC motor in order to vary the DC voltage going to the hub, but it's true that a DC motor controller is cheaper and simpler than the Brushless DC (ie AC) motor controllers. The reason you don't see many DC motors these days is because while they make the controller electronics simpler, the construction of the motor itself is way more complicated and failure prone, with spring loaded brushes and commutator plates and all of that. We used to carry a few options for DC hub motors but in general they aren't available these days.

      @patrickdrie 4 роки тому

      Its poweing the fixed stator, not the moving rotator. Also to get to the stator the wire is not going through the moving housing of the motor' but instead going near to axle , or even through the axle. THe axle itself is fixed. the bearings are sitting on the non-moving axle.

      Typically they are sold with the battery pack itself, since each rack mounted battery will general have its own custom rail design and a matching rack to go with it.

    In my country (Germany) riding any bike without a front brake on a public road is illegal. Doing so with an electric motor capable of pulling the bike at speeds of 25 km per hour or more is stupid. Doing so on a bike where the rear brake is a weak coaster brake is beyond stupid. (And yes, I know what I'm talking about, having converted three bikes to e-bikes as of today).
