Been there, done it. Required a lot of support time for 50% of the people, the rest were fine on their own. I couldn't justify that level of support unless it was paying its way, which it wasn't. So either I up'ed the cost to cover the support, or provided a more complete kit. I prefered the...

I fully intended to make a business of the friction drive, took time off work to develop the design, concept,business model etc. But ultimately I felt it was not sustainable as a business. Here are a few reasons why: 1) Robustness / Ease of Setup - Takes some skill/care to install and setup...

A longer swing arm mounting the motor could help. This will give more tire engagement for the same contact angle. I know Kepler used a longer swing arm. But I have never had the need with the tire pressuresi have tested.

Good question. The cheapest and easiest alternative to my fancy "Brain Box" is actually and very cheap off-the-shelf controller. The S06P magically works very well, at both 24V & 36V. The key is the ramp rate of the throttle, and ability to spin up these small motors well which is not the case...

It sounds the the geometry of you "approximate copy" might not be quite right. I have a video that describes the set-up process for my drive, this might help you decide which element is not right. I think it is this one: TeDcXKZfDpM But the key elements (from memory) are: - correct initial...

The links from that post worked for me...

Hey Everyone, Sorry about going incommunicado for so long. Life got a bit busy.... about the same time I realised that I don't think taking this project commercial is a good idea. I was actually pretty happy technically, and still use this drive as my main ebike, but the business case just...

Took your time with the cruiser. : ) What has it been three years? Bike looks great. How is the rural life treating you? Looks like your shed is a bit bigger than your last place.

Just thinking aloud but could you make an active chain idler, that doesn't rely on a spring to take up the slack, but actually moves the idler with a four-bar link type arrangement as the suspension moves.

Oh. Used about 350wh for the 26kms BTW.

Thanks for the ride Kepler and rp3. Was a perfect day for it. About 26kms all up according good to the GPS. Almost flew over the handle bars once or twice following Kepler over a couple of the jumps and slowing down too much. Glad I had you guys as tour guides. I had no idea where we were.

Sunday morning @ Lysterfield anyone?

Make it a weekend and count me in!
