E-Bike System

I have enough cells left to make a 7S7P pack for my kid's Razor E200 stand up scooter. I'm going to try to make it this weekend.

Hi there,
I'm planning to convert my bycicle to an e-bike with a direct drive rear motor, 12s LiPo. I believe my bike has a 28" wheel (not sure to be honest, tire says 28x1.40, but is that a 28" wheel or 26"?) and I'd like 45+ km/h and at least 25 km reach. Regenerative braking would be great. I'm planning to use 12s2p 5 Ah LiPo, resulting in 44.4 V and 10 Ah nominal. Which motor, controller and shop can you recommend?

I would like powerful and reliable components, not something cheap and upgrade later. So far I've seen Magic Pie II, E-BikeKit.com and other shops, but can't decide on one without customer recommendations.
