Frequently Asked Questions

What is the difference between a mid-drive and a hub motor kit?

Mid-drive kits mount the motor at the bike’s bottom bracket, driving the crankset and leveraging the bike’s gears for efficiency and torque. Hub motor kits replace either the front or rear wheel with a motorized wheel, providing direct power to the wheel. Mid-drives generally offer better hill-climbing ability and a more balanced feel, while hub motors are simpler to install and often more affordable.

Do conversion kits include a battery?

Most electric bike conversion kits do not include a battery. The motor, controller, throttle, and sensors are typically provided, but the battery is almost always a separate purchase. This allows riders to choose a battery capacity and form factor that best suits their range requirements and budget.

How difficult is it to install an electric bike conversion kit?

The difficulty varies significantly by kit type. Hub motor kits are generally simpler, often involving just swapping a wheel and connecting wires. Mid-drive kits, while offering performance benefits, require more mechanical skill, specific tools, and a more involved process of removing the crankset and bottom bracket. We recommend assessing your mechanical aptitude and tool availability before choosing a kit.

What kind of bike is suitable for an electric conversion?

Most traditional bicycles can be converted, but some are better suited than others. Steel or aluminum frames are generally preferred over carbon fiber for durability, especially with powerful motors. Ensure your bike’s dropouts are strong enough for hub motors, and check bottom bracket compatibility for mid-drive kits. Mountain bikes, commuters, and hybrid bikes are popular choices.

What is a torque arm, and do I need one?

A torque arm is a safety device that helps to secure a hub motor axle to the bike’s fork or frame dropout, preventing the axle from spinning out due to the motor’s torque. For any hub motor kit, especially those with 500W or higher power, a good quality torque arm is highly recommended, if not essential, to prevent damage to your frame and ensure rider safety.
