They must he joking. That is not acceptable. Its hard to tell from the pictures but make sure its just not release agent that hasn't been cleaned off.

Fair enough to be cautious. This is the same PayPal address that i did all my transactions with when i built my bike.

Re: Kepler Friction drive comes of age.

Put together this bike to use as a low cost commuter. The bike is an Aldi special hard tail that for the bargain price of $400, came surprisingly well equipped. Included hydraulic discs and Shimano SLX group-set. Installed my standard drive bracket but added a mechanical activation lever but this ti...

Sorry, I missed your post. Yes I am sure that bracket would be plenty stiff enough. Looks like a good off the shelf solution.

Re: Dengfu M09 Endruo/Freeride build log

What I have found is that it is makes a difference if you turn the bike on and let it sit without moving the bike or touching the pedals. If you do this the PAS is much smoother especially in low power settings and light pedaling effort. What I have noticed is if you just jump on the bike, start ped...

Re: Kepler Bottom Bracket Friction Drive For Sale (Finally)

I have standard drive brackets available however the design may not suit a folding bike due to the typical distances between the bottom bracket and the face of the tire. The drive is adjustable from 60mm to 110mm. The drawing in the previous post shows the drive set to 80mm. However the bracket lend...

Re: Kepler Bottom Bracket Friction Drive For Sale (Finally)

There are 3 possible reasons for this. 1 > Your speed controller is ramping throttle too slowly. 2 > You are not applying enough power. (Needs to be above 100W) 3 > The most likely reason is that you have not got the correct geometry setup on the drive. Please refer to the picture below. Drive9.JPG ...

Re: Full suspension mountain bike Friction Drive

Experimenting with knurling the motor can directly. No problems cutting the knurl on to the motor can and the grip on the tire is excellent. Time to do some testing. I am not concerned with accelerated tire wear with the small amount of power I am using. More interested in how well the knurl wears. ...

Re: Full suspension mountain bike Friction Drive

I have tried so many methods of getting reliable drive from the motor to the tire. Been down the polyurethane track and it does improve grip over a smooth metal roller but any moisture on the tire, and we are back to square one. This is a mountain bike so you are going to be very limited to when you...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

My grinding noises were from the steel reduction gear. There was nothing wrong with my X1, it was just loud, like listening to a cat on a fence moaning and screeching all the time but no way to throw a shoe at it to shut it up. A few people pooh pooed me and claimed the noise wasn't so bad, now the...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

I checked mine when rolling it backwards. You can feel the resistance of the motor gear reduction but there is no clicking. So you are saying the motor works under throttle but not pedal assist? Is that on all assistance levels? With the chain off and turning the cranks backwards, do you get the sam...

Re: Kepler Friction drive comes of age.

The mechanical conversion to lock the drive in using a remote fork lockout is really easy to do. The gravity spring is no longer needed and you just need to add a 4mm flat washer to the motor attachment bolt to lock the cable down. Lots of cheap options for remote fork lockouts (just google it).

Re: Kepler Friction drive comes of age.

You can get the regen to work without reprogramming the Arduino interface but you will need to change the setup within the Vesc. You will need to make changes in the App settings/PPM from "Current No Reverse" to "Current No Reverse With Brake" You will then need to re scale the Arduino output. In si...

Finally found a true MTB tire that works with a friction drive. I am not sure if the tire is new model but was very pleased to find it. Tire is a Schwalbe Smart Sam. 2.6" wide 29'er.

Re: Kepler Friction drive comes of age.

It sounds like its more an issue with the settings in the vesc. Make sure you have the max wattage set really high so it is taken out of the picture. Start with low current settings. Say 10A battery and 20A motor. Also make sure your 2 voltage cut offs are set correcty. See if it will stay engaged t...

Re: Kepler Friction drive comes of age.

Find a 140kv or lower motor. Flipsky have one that will suit that is a 6354 size.

I presume you have 20A cells in that 13S1P pack.

VESC recommends a max of 12S however the components are rated at 60v so it should be ok.
