Take a look at the video of this soon to be released electric bike. I saw it a while ago when it was still in its infancy, but a friend just sent me an email to check it out.
It is nerdy enough that I want one to ride around for sure, but I’m not sure if it has great utility as an urban car replacement or if it is just a cool new toy. If YikeBike wants to send me one to try, I’d be happy to test it out and report back.
