Before I bought my DR350 I built two electric bicycles - a rear tire friction drive with an RC 63mm motor that kinda failed because of the concept - but when it worked the very small weight and 600w of power felt amazing. The second one was a Smart Pie hub motor from Golden Motor, completely silent, weird handling because of the weight and finally had to be scrapped because the battery I needed was the price of the DR350. I studied electric propulsion for a year, more pages than I can remeber on Endless Sphere forum and alot of other sources and now I'm pretty sure I know the basics to convert my DR350 to electric if batteries would be cheap enough and have the required range. In every discussion I see on forums and social media there are the guys that understand the laws of physics and the ones that don't. A pure electric motorcycle has to have the motor in the frame not just for suspension reasons, but for heat dissipation, power delivery through wires exposed to flexing and damage from rocks etc, swingarm stresses from motor torque, much heavier axle and bearings, much harder to fix a flat etc. Tacita motorcycles have a gearbox and clutch. Any electric vechicle having a gearbox should raise a red flag regarding the engineering department. Tesla had a two speed but kept braking it so went single speed, Alta single speed from the start, Zero the same, diesel electric trains are single speed. You get the idea.
