    My RC Mid Drive with Single Stage Reduction

    Polygon finished! I have fitted the 9T sprocket on the motor and the 30T chainring. It all works very well. The 9T works better, but as mentioned by everyone else, it is more noisy. All that's left now to do is to ENJOY IT!

    My RC Mid Drive with Single Stage Reduction

    Thanks FZBob, you made me spent more money. I've ordered the 30T Wolf Tooth chainring. I don't think changing from 32T to 30T will make much of a difference. The main reason I bought it was that when I'm on the 50T at the back the chain line is very bad. With the 30T I hope to drop to 46T to get...

    My RC Mid Drive with Single Stage Reduction

    Thanks for the info. I will have a look. I like the Wolftooth products. I am using a 104 BCD spider. The new Rebel sprocket is also a 104BCD, so I would like to stay with this mount. The smallest I've seen on a 104BCD was 30T, with the spider interfering with the chain. My SRAM chainring is...

    My RC Mid Drive with Single Stage Reduction

    Thanks - The ISCG mount works really well. No movement on the motor. The battery was custom made from 18650 Sanyo 3400Ah cells - 4S4P, fitted inside a 30mm x 50mm rectangular tube. Animalector spot welded the cells for me. He has done a great job. The biggest BMS that fitted into the tube was...

    My RC Mid Drive with Single Stage Reduction

    So I took the bike for its first test run. The best part of the bike is that it still has the feel of my original bike, just a bit heavier. I had a pedal assist, with trottle, Bafang BBS02, Norco MTB and still have a torque assist Bafang mid drive MTB, so I think I can make a fair comparison...

    My RC Mid Drive with Single Stage Reduction

    Thanks! I do agree that the analogue approach these days are very primitive. I had a look at the Arduino when you first mentioned it on this forum, but first impressions was it's complicated and will slow my build down. Definitely the way to go and when I get time I will start the research. For...

    My RC Mid Drive with Single Stage Reduction

    I was hoping to set up the R switch for the max power and only use the run button when I need short bursts of high power. Don't think I'll lock it in cruise control. Not sure if it will work. I have read in your previous post about the Absolute max current setting. Mine is also set to 100A What...

    My RC Mid Drive with Single Stage Reduction

    I have finished building the Push button CCT for the ADC input to the VESC controller. Basically you can adjust the three selections (L/Middle/R) to any voltage you would like. You can also choose to hold the green button in for RUN or lock it in with the cruise button (latched). I have tested...

    My RC Mid Drive with Single Stage Reduction

    Just received the Rebel 90T sprocket. Somehow it ended up being only 3.5 mm thick. I did not ask for that, but it looks good. Hope it will be strong enough.

    My RC Mid Drive with Single Stage Reduction

    Thanks FZBob! Yes, I am planning to join the motor bracket to the battery that fits to the down tube. That should stop it from side ways movement. I assume the push button would have to be something like this.

    My RC Mid Drive with Single Stage Reduction

    So I've started the build on my 12 speed Polygon N8. For this ebike conversion the gearing on FZBob's bike is very good (22T front and 40T back). With the SRAM 12 speed the smallest sprocket is 32T, and a big 50T cassette at the back. Compare the two and FZBob is still better for keeping the...

    My RC Mid Drive with Single Stage Reduction

    I've been following this build for some time now and really appreciate all the very good suggestions. A huge thank you to FZBob for all the hard work he already put in. I've bought most of the parts, same orange motor, and will start posting some photos soon. I've asked FZBob some technical...

    Very nice battery and charger. Looks like a space ship with a mother ship charger. Will have to upgrade the scooter to match the cool look.

    Animalector's Ebike Builds

    Are the info on the display useful or is it just nice to have? If you drop the bike on it's side or just laying it on it's side in your car during transport, you always risk the change of cracking the lcd screen. Keep It Simple

    cut the whole pipe off and weld in an arch to go around the motor. It you get a good solid plate and someone that can weld, maybe.

    Animalector's Ebike Builds

    The question is, will 1 inch of extra clearance from the ground make such a big difference to the type of riding you are doing that it is worth taking the risk of cutting into the frame. Brave move - you do it first then I'll think about it.

    Yes Sean, we are spoiled. I live across the road from the Smithfield mountain bike Park that is behind JCU campus. Kepler, that is a very posh battery box, nice bike frame with lots of space.

    Thanks. I am planning to stuff all the gaps around the battery with firm rubber just before I close it up.
