HUB MOTOR VS. MID DRIVE: WHICH IS RIGHT FOR ME?

A hub drive motor is where the motor is located in the wheel, normally the back wheel. The mid drive motor is located in the centre of the pedals called the bottom bracket.

We will cover the advantages and disadvantages of each.

Hub motor:

The biggest advantage of these motors is that it is proven technology. It has been around for many years and requires very little maintenance. The components are sealed in the casing so it is maintenance free and very little can go wrong. It has no moving parts so there is nothing to wear out and it should last for a very long time. The hub motor does not add stress to your chain and gears. It is also much cheaper and a simpler motor.

The hub motor is doing well on the flats but is less effective on hills. Under normal circumstances the motor weight is not an issue. In the case of serious MTB the extra weight and the position of the motor at the back will compromise the suspension capability.

Mid-drive motors

The major advantage of mid-drive motors is the ability to power up steep hills. The weight is better distributed and that improves rough terrain handling. For serious mountain bikers that is important.  The motor is normally also smaller and lighter. Since the motor is located in the BB, changing a wheel is easier. The maintenance on the mid-drive is the biggest flaw. There are multiple moving parts, so much more which can go wrong. There is a lot of strain on the chain too and needs to be upgraded and replaced regularly. Then you cannot change the gears unless the bike moves. This can be tricky if you stop in the wrong gear.

Hub drive motors have been around for many years and have proven to be reliable, simple and durable. The mid drive motor is new technology, far more complex, costs more and has a better weight distribution.
