Okay, I will try the bigger rear sprocket. I've been looking at the torque graphs and the problem is that I get max torque at 175rpm, and with current gear that happens to be 15kmh, and that's why it feels slow when I accelerate from 0. With the new gear, max torque will kick in at around...

Hi guys! I'm Marco from Spain. I've built an electric dirtbike starting with a gasgas 450cc dirtbike and I installed a votol kit. The kit consists of: votol em 200sp controller + qs138 90h motor + custom 72V 20S10P 250A max discharge the battery. I'm running a 520 chain with a 13t/48t gear...

Awesome, tried everything you said and I can really feel the torque now. Might try to go to a 70t rear sprocket (if I find it) to have extra torque, since now I'm running a 13t to 48t and I don't really need the top speed

Hey! Yes, good idea, I`ll describe my system. I have a Qs138 90H motor joined to a votol em 200 2sp controller, with a full Kit I purchased that has screen and accelerator. Battery is a custom 72V 20S10P battery with samsung cells that can peak 250Amps of discharge. I´ve attatched 3 pics of...

Hey! I've built a dirtbike using Votol em200 2sp + qs138 90h motor. Finally, after almost a year I've finished the conversion. I'm running the default configuration on the controller, but it seems very slow compared to the specifications (13,5kw and 80nm peak power). I've not fiddled with...
