I am a big guy (400+ lbs, but actually going down) and I know I need a bike built to support my weight. I spent a lot of time looking over the bikes on supersizedcycles.com and I found the iZize Mt Trailz AL Electric Bike. It looks like it would be the perfect fit for me. I don't honestly know anything about ebikes or what determines a good motor/battery. It says the motor is 450 W from a DC Earth magnet motor and the battery is EV Rated SLA Type Rear Rack Mounted 24V / 10AH Pack. Help me out here, folks! IS that good? Will it give me the torque necessary to help with hills and such?
