1500w Electric Bike Ride

I built this fast Marin ebike for a customer using a 1500w direct-drive hub motor electric bike kit and 52v 14ah battery (using Sanyo GA cells). Other upgrades include Suntour SP-12 NCX suspension seat-post, Gel saddle and Schwalbe Marathon Plus MTB tyres.

It is wise to use a decent donor bike with good components - I wouldn't recommend fitting this kit to a bargain basement mountain bike. 2. If you have 8, 9, 10 or 11-speed rear cassette, this kit will only take a screw-on freewheel (7-gears at most). You may need to change your shifters and rear mech to accommodate the reduced gearing. 3. A rear torque-arm is recommended to prevent the wheel popping out of the drop-outs. 4. Make sure you purchase the correct wheel size - these kits are usually available in 26" / 27.5" / 28" wheels. 5. A good puncture resistant tyre, with inner-tube sealant as a back-up - you don't want to be going through the hassle of repairing or replacing an inner tube on one of these! 6. Electric bike hub motors will only fit on bikes with standard drop-outs (not thru-axles). 1500w Direct-drive hub motor conversions are ideal for fast cross country riding, but not really suitable for hard off-road riding due to the extra weight in the rear wheel.
