This is an electric Haro mountain bike that was put together at our shop on a customer’s bike. It’s one of the few ones we’ve done with disc brakes and suspension forks. Using the modern suspension forks, it’s generally only possible to install the 200W mini-motors because the higher powered motors have larger axle nuts that don’t sit well with typical suspension fork dropouts; the mini-motor seems to be quite a bit more generic for this purpose as the axle nuts and washers are smaller and nearly always fit snugly into the fork dropout. The disc kits aren’t common but this one worked a treat. It’s not always possible to use disc brakes because the motor can rub on the brake caliper depending on the brakes; usually they work ok but you need to be prepared to revert to V-brakes and pads if it doesn’t work out or else you’ll need to do some fine adjustments to get everything to line up. The tube batteries are a really good solution for these electric bikes we’re finding now – hardly any problems and the performance is great. This is a really nice commuting machine and it’s still pretty light, the kit only added about 6kg all up.
