Allex
100 MW
Yet another light and empty bike will be "destroyed", filled with heavy stuff like batteries and a motor
At first it had to cope with this MAC 8T motor and HK lipos @ 37V20Ah.

I wanted to try something new, so decision was made to run a Bafang BBS02 750W along with a hub gear at the rear, Shimano Alfine 8spd.
I wanted to remove ugly sprockets and also be able to choose a gear while not riding the bike. I know one person that had a good luck with his Alfine 8 and his Cyclone motor at 2kW, but this hub was one of the first models from Shimano, and we all know that companies strive to components lighter and therefore more bittle. It will be interesting to see if it is up to the job. I has been told that the new one, 11spd. with oil bath gear system will not take the stress of a ~1,3kW motor.
Found https://www.taylor-wheels.com/ in Europe, that had OK prices on a complete set with 26" rim, lace job and everything you need to mount Alfine:
26" 32 hole XM319 black rim with black spokes
Shimano Alfine 8sp 32 hole hub black for vertical dropouts
Sprocket, Shimano Alfine 18
Shift lever, Shimano ALFINE 8 speed black
Shimano Disc brake 160mm
Shimano Alfine chain tentioner
Total: 308Eur(344USD) with shipping
This is what you need to install the whole thing, important to have those green/blue(one goes to the right, another to the left side) Non-Turn Washers to secure the Alfine Axle in the dropouts. The hub also uses Shimano c lock rotors, so you have to get that instead of a traditional 6-hole rotor.
Yeap, SG-S501 is a lovely piece.
Oh and we need a chain tentioner
On the bike:
Chainline with stock front chainring
With 18T at the back(you can shoose various sprockets from shimano) and 44T in the front I should be able to pedal up to 45-50km/h, according to this calculator:
