the bike looks cool overall, but i too have some concerns about electrifying a bike. they've been fantastic 100% mechanical machines for generations now, and that holds appeal to me. does that make me a retro-grouch?
i'd give one a try just to know, but i think my inner bias would probably taint my impressions unless it was super-awesome, mind-blowing, revelatory experience, like "oh my god, this completely changes EVERYTHING we've known about cycling for the past 100 years!"
