I'm designing a velomobile to replace my car. I need something to protect me from harsh weather on my ride to work and the shops. It will be almost entirely home made, except for the wheels and bike components. Maybe I'll build the rear wheel myself, but I already got a good deal on the front wheels I want. It might get active electronically controlled suspension with lean/anti roll as well. I need it to be easy to build as I don't want to make huge molds, so I'm going with a combination of plywood and carbon fiber. The frame and suspension parts will be 6082-T6 aluminum. With a tilting steering wheel and "lambo-doors" it should be easy to enter and exit. I want it to be comfortable, not too laid back and visible in traffic, yet fairly aerodynamic.
I'm not decided on how to power it. I am limited to 250 W in Norway, but that's ok. I'm designing the frame so that I can use a Bafang crank drive up front, or lpaced in the middle behind the seat if I want to. That's the most practical option for me as I can then use a crank with a narrower Q-factor. There is also room for a hub motor in the rear behind the seat if I go that route, but I'm leaning towards a Bafang-unit for now due to its compact form factor. Battery size will be flexible depending on the needed range at any given time. There's a lot of room for batteries on each side of the seat under the floor.
Wheels will be 26" all around, with a fat bike rim and tire in the rear. Downhill wheels in the front with 20 mm hubs. The ability to lean according to G-forces using an accelerometer will reduce the side load on the wheels, but don't plan to do any tecnical racing with it. Air shocks all around and about 80 mm of travel.
There's easilly enough room for a 60W flexible solar panel on the roof, but I don't think I'll go that way.
Hoping to keep it around 50 kg, but I don't think that's realistic.
