Rocket e-bikes are typically delivered in 3-6 working days.

If a battery upgrade has been chosen, expect delivery in approximately 5-8 working days.

Despite their cruiser style, there is a large amount of adjustment that can be made to Rocket e-bikes.

Extra pads can help to raise the saddle height, or alternative handlebars can be fit to give you a more upright position.

If you are concerned about the size, get in touch with us to discuss modifications we can make to the bike before delivery.

If you are on the taller side (6ft+), we would recommend the GTS line up as these have 24” tyres and so are more suited to taller riders.

All Rocket e-bikes come with a 12-month manufacturer's warranty on the motor, and a 6-month manufacturer's warranty on the battery.

Please Note: Batteries need to to stored correctly or the warranty will be void.
