OK, scratch "silicone" from my previous comment and substitute "polyurethane" in its place. As skateboard wheels are made from polyurethane, setting a 10mm ring to bond around a motor's cylinder might achieve a similar level of grip without the bulk of adding an extra wheel drive to the mechanism.

In terms of grip and knobbly tyres, might it be worth exploring the opposite end of the scale to sandpaper?.. I wonder if a flat-surfaced low-shore silicone ring moulded around the motor cylinder - and having, say, a 10-15mm thickness - might impress into the harder rubber of the tyre, when...

I found ebay had a lot of them - for around the $4 mark.

Thanks for this Kepler - it's very useful. I've given up on the servo-tester hack and have an Arduino Nano board on order.

Thanks for your suggestions, Kepler. Yes it is a hall-effect throttle. I didn't have any luck following your wiring scheme... pic below (sorry for poor quality - the green wire from throttle going to the centre pin of where the pot used to be). I firstly hooked up the servo tester - with its...

I've also acquired a bluetooth card to add to my Kepler Friction drive bike. It works... but it uses the ports currently assigned to my twist throttle. I've tried rerouting the throttle into the Vesc through the servo cables using the hacked servo tester method (as shown here...

Haha - thanks Kelper. The stealthiness of your design is why I opted for it. I've also stripped all the original front and back derailleur gear stuff off the bike and replaced it with a Sturmey Archer 5 speed IGH - adding to the understatement, I think :) BTW - I had some BB shell slippage...

Thanks for the BLDC info Kelper. I followed the instructions and below is the screenshot after doing so - not identical to yours but it looks pretty close to me. I changed the Lambda to 10A, but couldn't work out how to "spin up" for this entry - I so just clicked on "Write configuration" and...

I’ve managed to run the three cables from a saddlebag-mounted battery through my aluminium seat post and seat tube to get the 'stealthy' bike set-up. I did this by using thinner 12AWG PTFE wire around the inside of BB Shell and out through a 10mm hole in its base. I added an eccentric BB to...

Thanks for the tips. I pulled the motor up to just touch the tyre and that worked. I also added a spacer washer to the top locking screw - as this increased the screw's shaft diameter enough to stop the motor rising up so far it scraped on the bottom of the kickstand plate. Both the top and...

I'm having problems getting the friction drive to engage. On twisting the throttle, the motor moves into contact with the tyre - as it should - but then it immediately drops back a little so that the tyre is no longer being driven. This happens even though the motor continues spinning at the...

Thanks for the info. Mine's wired like that too now and the throttle's working as it should.

John - I'm wiring everything together... which is going well. I have a throttle + the appropriate Vesc connector for it (as discussed a couple of pages back). However, my Vesc board has a row of seven pins rather than the six shown in the set-up manual image. Can you direct my towards which...

9.4Ah €350. In the UK it's about £240. It's a good price I think.

LOL - I did wonder if it could be that straightforward :) ... and then I got lost thinking if cells in parallel/Ah, etc, would affect the input values. This is the battery I'm likely to get. 9.4Ah at 36v would be an ideal pack for me. Husqvarna are respected brand in the power tools world. This...
