The tank.
I've made the first frame with low positioned battery out of an old donated bike named Taifun with front Chinese spring fork, bat. 36VNom@2232Wh, 25Amp Chinese controller and 6kg heavy motor. Didn't have much of an idea what to do with it at first so I rode town mostly. Randomly ended up in the mountains and liked it a lot but my wrist were not having it at all due to vibrations. So I've started creating completely new frame in 3D with a proper fork and battery located at the front dimensions mostly derived/updated from V1.0 :) . Using phaserunner with CA3 I can get up-hill torque support at a certain level to keep the speed around 10-15 km/h and kickscoot at the same time ending up with great workout and a lot of trail and DH fun rides, thumb throttle rides also possible. Thanks to Grin for this amazing product.
Right now I'm working on the new frame for next season, completely closed up sheet structure, scooter will be about 8kg lighter in total hoping for 25kg and about 48VNom- 1500Wh battery pack.
Current frame is 4 CrMo tubes 18x1mm and 14x1 mm mig-welded with some reinforcements at the lower structure due to excessive flex cracks.
Front fork is Fox Talas 120-140-160mm depending on the trail conditions lower is better for workout but not much for trails.
The battery is modified standard (6s2p) VDA format now 12S @ prismatic 62Ah a cell 2732Wh this will get me 3 hrs in the mountains plain throttle, ride distance around 70km (200+km of flat surface rides) all distance values depend on, we all know what.
Shimano XT brakes 203/180mm discs.
Total weight is 33Kg.
I've got over 80 hours of test rides into it and counting.
V3.0 is under construction.
