FAQ

+ 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.

Fun to ride

This bike is fun to ride. The stick seat is a little to hard and minimal, so I plan to upgrade it. I will also likely add a rack, and that will make this the perfect shopping mobile.

Simple & Does What it's Supposed to

I bought 2 Espin Aero's and they are a great commuter bike. One can't tell they are electric as the batteries are built into the bike. Provides enough power on level one, level 2 is the intermediate assistance and level 3 one pedals quite easily at about 18mph. Because this bike is a pedal assist bike, it provides for a good workout too. Great all around e-bike.

I sure wish it had gears

It's a BEAUTIFUL bike. Amazingly light, fun to ride, and a great price.

BUT...I can't ride it up our hills. It would be perfect for someone in a flatter area.

Manual brakes are a little wimpy (again - because we have hills).

But the simplicity of the controller is great.
