hello all,
My hardtail build went well, but is not of mutch use exept for recreational fun, low range, I can't pedal as fast as the motor (44-18 single speed), and not weather-proof. So I started drawing and gathering info for a new build, a tadpole velomobile with an open cokpit.
I was posityvely influenced by the builds on this forum, great stuff.
So my project is to build an eficient alternative to a car, on distances up to 30km (60km two way).
3 wheels for stability, 20" front and 26" rear, maybe a moped wheel.
tadpole configuration, way more stylish!
Great or at least ok aero.
Rear wheel drive, using a car alternator for variable field and infinite motor gearing. (but a watercooled colossus motor would be great!)
sensorless 12 or 18 mosfet bmsbattery controller.
i'm not sure what cells I should use, but from my low power requirements, 20ah TS cells would do the trick and would be cheap.
48 volts, to start with.
Here my firsts drawings,

started the actual build a week ago, but I forgot my phone with build pictures on it at the workshop!
I'ts going good so far, I use 17.2mm hydro tube, bent with a simple but trusty hydro bender.
The bottom tubes, the front boom, and the seat tubes are done, and thack welded in place.
I am now gathering info on steering angles and direction set-ups.
sorry for my spelling!
