Frequently Asked Questions

Does my Bosch motor require regular service?

Bosch motors are not designed to be serviced and should only fixed if they start to fail. The motors are sealed for life and if kept dry will do in excess of 80,000kms without problem.

My Bosch motor sounds a bit rough, should I just keep riding it until it stops?

Standard shipping normally takes 3-5 days. Next day shipping is available on all domestic orders (for an additional charge). International shipping times depend on the products and destination (estimated at checkout).

Why do the bearings fail, are they bad quality?

The bearings fitted to most Bosh motors are extremely good quality and well sealed, but although a bearing is classed as “sealed” it is not waterproof! They are at best water and dust resistant. This is the same for 99% of the ebike motors on the market.

Why don’t they seal ebike motors against water and dirt?

It would be very easy to seal a motor during design stage, but seals add drag and drag equals battery consumption. It would be commercial suicide for a manufacturer to release a motor that achieved 1 km less battery range than their competitor.

Will fitting a tuning dongle damage or wear my Bosch motor?

We have never seen any damage caused to a motor by the use of a de-restricting device.
