Riding up Pikes Peak on an Electric Bike Part 2

[@claytonpflieger9394]

Marc, thanks for your interest and I know you'll enjoy your electric bike! There are several kit vendors and I used eBike Kit. Their customer service is excellent. Shop around and pick what's best for you. In any case, my strongest advice is to use a torque arm with your installation. Without one, the motor axle will rotate within, and tear up the dropouts -- even on a rear-wheel application. On my install, I wasn't able secure the torque arm adequately with the supplied wittek clamp. So, I modified my torque arm and attached it to the disc brake mount. That worked perfectly. Welcome aboard and ride safe!

Thanks for the response and advice. I’m going to try end of June.

Cool. I found you by searching for "electric gt avalanche bicycle". I own an avalanche (not sure if it's 2.0 tho - probably not) but I am curious if you have any advice for converting mine to electric - before I get started (on a real tight budget). Thanks!

Marc, I’m sorry I didn’t see this earlier! Advice: use a torque arm. Conventional bike frames (dropouts) are not built to support axel torque from a hub motor. But, with a torque arm, it’s no problem at all because the torque load goes through the arm and not the dropout. Good Luck!

I'm thinking about trying. How many amp hours did your battery have? Mine is 702. Do you think that that would do?

Thanks Allen! I left Crystal Lake Reservoir with a fully charged 48 Volt, 13 Ah (625 Wh) Allcell NMC lithium ion battery and it got me to Devil’s Playground. I was pedaling the whole way and averaging about 10mph. My wife was chasing me in the truck and we had a 36 Volt, 15 Ah (540 Wh) Allcell battery along aaa a spare. I swapped it out and made the summit. I hope I see you on the mountain this summer because I’m going to try it again! I should have a new battery by then. I’m looking at a 51V, 14Ah (712 Wh) battery and more athleticism on my part! 702 Watt hours is a good sized battery. With some strong pedaling you should have a good chance of riding all the way to the summit. If you have a geared motor, you’ll do even better because those are more electrically efficient than the direct drive motor I used. Good Luck!!!

@@claytonpflieger9394 I started at Glen Cove and made to the top, on Tuesday. Then recharged and went from North Pole to Glen Cove. 52 volts 13.5 amps. Today went from top to bottom.
