Nothing more yet, rock solid so far Since it's starting to rain more frequently I will likely install the enclosures soon to make it water proof, else too many days I don't ride by fear of getting caught in a storm I'm also considering doing a version that drives directly the rear wheel with...

Long overdue update but a new version, motor moved from the rear of the seat to under the frame so that the flexing of the spindle doesn't change chain length significantly, works flawlessly I have enclosures printed and ready to the VESC but since I'm at the dry season I haven't bothered yet...

Finally after a long time it’s rideable, first test went really well, it was just a short ride around the block since it is late First thing that needs to change is the controls, right now it’s the same as my friction drive, 1 button press 25% torque, 2 50% and 3 100%. Right now it’s really...

It doesn't look that bad being huge, I may paint it black to mask a bit Screwed up a bit on the motor mount design, it cover the rear shifter cable mount, a bit of dremeling may solve that, in the future I probably will do a new mount in front of the pedal, I avoided that because the downtube...

Nice to hear that Yeah, the VESC firmware has a problem with tracking at low duty cycles, on low power builds or/and ones that use a non optimal gearing it gets really apparent I plan to play with that, instead of dropping the Kv, lowering the voltage may also work since you would increase...

This is actually a good idea, I will think about for a while Probably the slack side would have to have a pre load, if we could measure hpw that pre load changes, a pedal torque value may be calculated from it

Thanks, they are custom laser cut, there is a shop in my city that does this kind off service ridiculously cheap, if I were to convert to dollar, all these parts, minus the chain, would be $26 Shiny ones 304 stainless, and black ones carbon steel, in case the stainless ones wear too fast I...

Inspired from all of you guys, I've started working on my own The previous version was a friction drive, but it didn't work that well and for some reason I blew a lot of tires with it

I've been silently following this build for a while If there is a dream bike for me, is someday building a similar frame as that, can't wait to see the results Well done Chambers

Didn't, but it's $170, no deal, but shipping of anything is ridiculously expensive to get it here, I'm not on the US

Thanks, it's not that bad If this is to be trusted can be had by around $150...

Padja, do you recommend a tester that can do more than 5 A charging and doesn't break the bank? I want to play with fast charging profiles and thermal control in the future

I'm using MotorAnalysis, free and powerful, more intuitive than FEMM https://motoranalysis.com/

Awesome project Justin, good luck on it If I heard it right do you plan to also put some solar panels?

Good point The thing that I would do is never connect the chargers in parallel first because of small differences in voltage Connect first one to the pack and then the second I want to try that for a long time, if I do will post here
