Size Guide


+ What is an electric bike (e-bike) and what makes it different from a regular bike?

An electric bike is just like a regular bike, except for 4 main electrical components: the battery, motor, controller and display. Other than that, it will function and ride just like a normal bicycle. 

The Espin e-bike is a pedal assist bike, which uses the motor to increase the power created when you pedal. So it rides and turns just like a regular bike, it just makes riding easier, especially uphill.

+ What is Espin made of?

Espin pedal-assist e-bikes are made from 6061 aerospace grade aluminum alloy.

+ Can I ride my Espin pedal-assist e-bike in the rain?

Yes, we have waterproofed all the wiring and electrical connections so it can withstand rain. Of course, one should not let the bike just completely soak in the rain if possible, but there is no need to worry about riding in rain.

+ Can I assemble it myself?

Yes! The assembly takes less than 15 minutes and we even provide all the tools you need. If you run into any issues, you can follow along in the assembly video.

+ What maintenance is required?

Maintenance is exactly the same as a regular bike other than the four main electrical components: battery, motor, controller, display. You should do basic tune-ups on your bike after the first 100 miles. Regular tire pressure checking is important as you want to keep your tires inflated for maximum riding comfort. 

Other than that, the electrical components should require minimal maintenance and if any issues arise, please follow the instructions to diagnose the issue, which will be included in the user manual. If you are still unable to fix the problem, please submit a warranty claim and we will process your claim as soon as we can as we understand you want to get back on the road as quickly as possible.
