Hi all,
I'm looking for a kit for my hardtail mountain bike, image attached. I've also attached the gradient profile from map my ride home. The distance of my commute is about 12 km (7.5 miles) one way, and I have no opportunity to charge it at my destination, so I need a range of at least 25 km (~15.5 miles). I plan to pedal during acceleration and during the hills, however at the end of long days I am so tired I really don't want to have to pedal hard. My goal is a cruising speed of 30 km/h (20mph), regardless of gradient, with a total load of around 135kg, including me, my cargo (in panniers) and the bike (I'm 6ft tall, 90kg/200lb).
From what I can gather I'm thinking I should use a 25 amp controller, with a 36v 15 amp hour battery. At the moment I'm thinking of ordering a PING battery, but if someone can suggest something cheaper or better at a similar cost that would be appreciated. As for the motor itself, other than being a rear hub motor I'm not sure which one I should get, and your recommendations here would be greatly appreciated. The bike frame is aluminium so I also feel I should chuck a torque arm on the rear, and I'd also like recommendations for this.
In case it doesn't show up in my profile, I'm located in ACT, Australia.
My budget for this build is $1000 for the battery and motor kit.
Thanks for your suggestions, Jordan.
