ya that picture posted on there website shows sla batteries weird. and if thats the geared hubmotor i think it is
there have been problems with the controllers, in the past. price is way to high.
you can get this kit without the bike for $649

its a better hubmotor, mind you the batteries are cheesy
or put your money towards better lithium and go for this kit i have it works great you supply your own batteries
