How much do your bikes weigh?
You can find the weight of all our bikes in the specification section on each product page.
How long will the battery last?
The range of the battery depends on a variety of factors, body weight, bike weight, terrain and wind conditions. We recommend to use all the power modes available to optimise performance and battery life whilst monitoring the range on the display unit. For Bosch bikes you can calculate and plan your ride using the eBike range assistant here.
Can I make technical modifications to my ebike motor?
You definitely should not do so, as this will invalidate the operating licence and tuning is prohibited by law. With tuning modifications you change the tested functionality of your e-bike and thus endanger yourself and other participants in traffic. In addition, your insurance company may refuse to pay benefits in the event of damage.
Can I test ride an ebike?
We would recommend you use our dealer finder to see if your local bike shop has a demo model in stock for you to try.
Where can I buy your bikes?
We sell our bikes exclusively via over 300 specialist bicycle retailers throughout the UK. You can find your nearest retailer using our dealer locator. Learn more about why we support local bike shops here.
What quality guarantee do you offer?
