Size Guide


+ Will I be able to reprogram and lower the speed down to 20 mph to comply with Tier 2 requirements?

Yes, you can lower the speed. 

*Note: California has categorized electric bikes into 3 tiers:

Tier 1 – pedal assist bikes with a max speed of 20 mph and less than 750 watts of power

Tier 2 – Throttle on demand bikes that have a max speed of 20 mph and less than 750 watts of power

Tier 3– “speed pedelec” bikes with a max speed of 28 mph and less than 750 watts of power

+ 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 eBike 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 eBikes 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.

Love my Ebike!

Man do I love my new ride! I feel like I have a new lease on life!
I used to ride my bicycle to get around in my youth. This bike makes me feel young again. Such a feeling of freedom! I look forward to hopping on my Espin Nero as often as I can! Thanks! John

Nero changed our lives,

My wife and I are in our 60,s . We both got Neros and we love biking every day. We never would get out and now we ride them every where. These bikes are awesome. I have rented other more expensive brands when traveling and have been disappointed , Espin is the best in my opinion.

best ebike ever

Love the large nobby tires, extra 3.7 mph when needed up hill, power when needed. Step thru very easy to get on/off.

Mike O'Neil
6 months and still going great

Just an update. I love my Nero! The Battery lasts longer than I do (I've yet to use more than 60% in a single session) , the bike is comfortable, and trouble free. I'm a little jealous that the newer bikes come with a 750 watt motor. First generation bikes only have 500 watts, which is plenty 95% of the time, but on steeper hills, it struggles dragging my 200+ pound carcass up the hill.

If you want to tough, strong bike that can do anything, the Nero is hard to beat. Probably impossible to beat at the price.
