I have an Aerostream GT Cruiser bike with a kit I installed from e-bikekit.com. It's a front geared 350watt motor and I drive it with a 10ah 48V LiFePO4 pack mounted on the rear rack. The bike also has internal 3-speed gears in the rear hub. The 700C wheels on the bike have 14 gauge stainless steel spokes on the rear, and the replaced front wheel with the motor came from e-bikekit.com with beefier 12 gauge spokes.
I'm finding I'm breaking spokes on the rear wheel more often than I would like. Could be because of: more weight on rear wheel (battery); generally driving faster and braking more; other? I myself am no lightweight at 240 as well.
Trying to figure out likely cause and possible solutions:
- just replace spokes as they break?
- re-lace whole wheel with thicker gauge spokes like are on front wheel (not sure how practical this is)?
- re-lace whole wheel with butted 14 gauge spokes?
Any experience or ideas? (other than go an a diet!!)
