Hi,
I was dreaming of building my own bicycle till i was a child and had a ride in an alloy alleweder velomobile. now, grown up (still childish) its time to make it happen. first i thought of welding some kind of short recumbent out of steel but i did not have a shop nor appropriate tools. im also movin to big city during the next 2 months. riding a bent during rushhour is kind of masochistic. so i decided to built a GRP-frame with cruiser-geometrics.
GRP is easy to work with and needs only simple tools. all stressed parts are goin to be sawed/drilled/grinded alloy profiles and tubes. its been built around a positive mold out of foam. then the foam core will be removed, first mechanicly and then melted with acetone.
building start is in about 2 months after my move to big city. im not in a hurry gettin it done but i have to put it out of my head and into discussion before gettin insane
during the last weeks ive done a lot of sketches, improved them, throw away, did it again and so on. atm this is my favorite, but may change till building starts.
actually im doin a CAD drawing to figure out some measurements. (when i teached that damn program to do what i want )
desired specs so far:
- 26" x 2.0 - 3.0 tyres
- nuvinci hub
- discbrakes f&r
- front suspension fork
- 170 kV motor & middrive gear ratio for about 40 km/h top speed and 75-80 pedalling cadence (@max hubgear ratio)
- motor and gears built in motorbox out of alloy inside frame, accessible from bottom. maybe some kind of scoop for cooling purposes
- 36V 15-20Ah lipo or lifepo
- all wiring and cables inside frame, clean and smooth lookin.
thats it for now. you guys here on es are amazing and doin great stuff, i get a lot of inspiration out of ur builds and i want to give something back. maybe someone gets inspired by my project as well.
have a nice day
