Can I ride my Espin pedal-assist eBike in the 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:
Why am I receiving different parts than expected?
Due to the shortage of supplies, certain parts may be different from what is listed on the spec list. In order to ensure that we get you riding on your new Espin bike as soon as possible, we've had to replace certain parts with other brands of a similar level. Potential parts that may be affected are the tires and derailleur.
How do I maintain the life of the battery?
Please make sure to charge the battery once every 3 months if it is not being used for an extended period of time. This will help maintain the life of the battery. Failure to do so will result in a loss of range per charge.
What is the range on a single charge?
Each Espin Bikes has a different range. Please refer to the specific model's product page to find the range of the battery.
How long does the battery take to fully charge?
A full charge takes approximately 6 hours. The battery is detachable from the frame so you can easily charge the battery when you are at home, work or even while you are sitting at a coffee shop.
How long until a battery needs to be replaced?
The battery is expected to last about 2-4 years or around 500 charge cycles.
What is the max speed?
All Espin Bikes have different top speeds. Please refer to the product page of the specific model to find the top speed.
What type of tires does Espin use?
Espin pedal-assist eBikes use Kenda Kwest 26 x 1.95 tires with reflective strips for safer night riding. These are solid tires that are ideal for city riding. Soft enough to give you a comfortable ride yet hard and thick enough to handle sharp turns and not get interrupted by small sharp objects.
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.
Can an Espin be serviced at any bicycle shop?
Yes, any bicycle shop can make repairs on your bike. If you would like recommendations for bicycle shops in your area, our customer support team would be glad to assist you.
About Electric Bicycles
What is an electric bike (eBike) 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.
Do I need a license to ride an eBike?
No, federal law treats electric bicycles just like normal bicycles as long as they are limited to 20 mph while being powered by the motor and has less than 750 watts of power. Each state has different speed restrictions so you should check your DMV for additional information. 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
Espin pedal-assist eBikes are Tier 3 electric bikes, except for the Flow which comes set as Tier 2.

I ordered the Nero on Black Friday during Espin's sale for $1149. Wow! What a steal! This bike is awesome. This is my first electric bike but if you are in the market for a sturdy, powerful, all terrain fat tire bike the Nero is the bike for you.
The assembly was very easy and straight forward if you follow along with their video. I have some basic knowledge of bikes but had never assembled a bike before, and I managed to put it together in 45 minutes while taking my time. Battery was ~75% charged upon arrival, so I plugged it in while assembling to add some more juice. I noticed the front disk break was rubbing after putting the wheel on, so I took some time to tweak it until both sides were positioned correctly.
First ride out I took it 20 miles using moderate petal assist and moderate throttle and used up 2 out of 5 bars of the battery. I was mostly riding around pretty fast too, so the range was impressive. The bike is heavy, as expected and huge. My sister (5'6) took it out for a spin, and it seemed very large for her stature. I'm 6'3 so it fit me well but it is still big to maneuver around. The top speed I was managing in PAS 5 was around ~23mph and I'm in the works of figuring out how to go into the settings to increase it. Off road the fat tires really smooth out the bumps and you feel like you can conquer any terrain, on the pavement they were not too noisey. The hydraulic breaks are also very nice to have. You need to have some stopping power for a 70+ lbs bike going 20+ mph. Long story short: big, powerful, good range, awesome!
I got the bike today so I have yet to see how it holds up, but I'm sure that with Espin's build quality it will last a long time!
100% SATISFIED - LOVE THE PRODUCT AND CUSTOMER SERVICE...
Route Package Protection
Very happy with the eBike itself. However, included instructions are not complete. The booklet describing the electronics for operation are printed in such a small font that even with reading glasses, it was too small to read. I had to scan it in to the computer, magnify and print. Supplied suspension fork instructions are for a retrofit installation only, with no description of possible adjustments or settings. No use or mounting instructions for some optional smart phone holder parts, wheel reflector mounting instructions, or how to use the mounting bar diameter adapters for the optional rear rack carry bag clips. There are also 2 stud mount reflector squares that I can't find any sort of mounting holes for. I suppose you could add the white reflector to the front fender mount assembly. No idea what to do with the other (rear) red reflector. With current seat attachment hardware changing to a different seat will be difficult. I damaged one of the weird electrical cable connections after multiple connect / disconnect while routing cables. There is a headlight issue that would only be noticed if you damaged the extension cable as I did. Normal conditions, the headlight with extension cable attaches to the optional front rack. Temporary fix until an extension cable can be acquired: the headlight attached to the front fender mount using the supplied bracket will be pushed out of position by suspension fork compression if the optional front rack is installed. You could also remove the front rack or bend the headlight mounting bracket to solve the mounting issue.
