Swytch Wheel Resistance Test - Brompton versus 26inch wheel

- In this video I try and demonstrate how much resistance there is in a Swytch kit e-bike wheel. I test with a 16inch Brompton wheel and a 26inch wheel. The comparison is interesting and I hope you find the video useful.
Hi Mike
I recently bought a Swytch kit.. and was having similar resistance issues. I went to a Bike shop in town - just in case i had over tightened something etc.. Apparently they DO indeed have resistance.. but this gradually lessens as the wheel gets used more.. the Bearings etc will settle. I asked Swytch (replied just now) and they agreed there is resistance - especially on Bromptons due to the smaller wheel. Time will tell if they truly "loosen up".. Hope that helps.
This is interesting. Thank you for your extra research. I don’t think that the resistance is too much of a problem , ot just seemed a bit disconcerting, especially when compared to a larger Swytch wheel.
@@mikeknowles6063 I've had mine for almost 300 miles on a 26 inch wheel. There has been no lessening of the resistance.
Two questions about the Swytch kit:
1. What was the difficulty of installing the medal sensor? All other parts of the kit look easy.
2. What is the cost of the Brompton kit?
I would say that the pedal sensor installation was easy once I worked out which parts to use to assemble the magnet ring and where to place the sensor. Check out the installation video “installing a Swytch kit on a Brompton” on my channel for more details.
The price of the kit changes depending on which battery you chose, and how long you are prepared to wait. The Swytch website will have the up to date pricing for your region.
Can you do a comparison of the swytch and the Brompton Electric first party?
Sorry, no, I don’t have a Brompton electric to compare.
Is the difference due to the resistance of the wheels or is it the physics of the weight being further away from the center of rotation?
It’s not the most scientific test in the world, but I would say the difference is down to a difference in the Swytch motors used. The one in the 26 inch wheel is their standard motor. the one in the Brompton wheel is a different, much slimmer motor. There may be a small factor accountable to the larger diameter but not this much.
I have the same problem, but it impacts my autonomy by 40%
Maybe get this checked out at a friendly bike shop
Swytch boost no resistance without assist. That's your answer.
Thank you for leaving a comment. I’m not sure that I understand what you are saying, but thanks anyway.
@@mikeknowles6063 To Quote Swytch "With the brushless technology, you’ll notice no resistance while you’re out on the road - even if you’re riding with the Power Pack switched off. " Mike, Thanks for testing a showing the true state of affairs. Rather false advertising, though in practice, probably not noticeable with an adult's weight and gravity pushing the bike along. Did you notice the drag before you tested for it ?
@@SimonBrowneNZ The drag is not an issue whilst riding, and I hadn’t noticed it before someone commented on my build video. The Brompton is mine, and the 26 inch wheeled bike is for a family member. Whilst I had access to the two bikes I thought a comparison video would be useful.
