Wind resistance on a pedal car (or any car) is almost certainly always massively lower than on a bike. Cyclists are the least aerodynamic thing on the road, it's much more of a problem than weight.
Velomobiles like that yellow one are known to do 50+ miles an hour. Not special ones, no land speed record modifications.
Good work, Keep it continue.
I would like to get one of these with Lambo shell ! LOL
Not sure where you are located, but you may run into an issue with your local laws. I know here in virginia anything with more than 3 wheels(non stability) isnt considered a bike, you may have to register it. Otherwise that looks bad ass, enjoy it.
i like it. i've seen two rhodes cars here recently, but they're pretty far out of my crazy bike money range. i'm not sure if i could make one myself.
