General Questions
Related to Espin

What is the difference between Espin’s Sport and Flow eBikes?

The Sport comes in a 17 inch diamond frame and is for riders looking for a more sporty and aggressive riding style.

The Flow is a European inspired design built for the urban commuter who wants to zip through traffic and ride comfortably. It has an elegant 17” step-through frame that allows you to mount and dismount easily and safely anytime you want.

Can I ride my Espin pedal-assist eBike 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.

How much does an Espin pedal-assist eBike weigh?

Each model has a different weight. Please review the product page for the specific model to find the weight of the bike.

What type of brakes does the Espin pedal-assist eBike have?

The Espin pedal-assist eBike has 160 mm dual piston hydraulic disc brakes for both the front and rear wheels.

What type of saddle does an Espin pedal-assist eBike have?

Espin pedal-assist eBikes come equipped with the Selle Royal Freeway saddle with a soft-touch cover and shape memory. Our saddles use slow fit foam which is a visco-elastic material that molds to the rider’s body and guarantees a uniform weight distribution. Our saddles also reduce shock and vibrations to give you the most comfortable ride.

What are Espin frames made of?

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

What is the maximum recommended weight limit?

The recommended maximum weight limit is ~275 to 300 pounds depending on the model.

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.

Technical Questions

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.

Great Bike

Fit and finish is great

The derailer needed adjustment
The geometry of the frame and handlebars is a bit difficult for a short person

Problems with bike

I have multiple problems with the operation of my bike, First, the limits on my derailleur were not set correctly and the chain fell off twice and resulted in a visit to the bike shop for repairs. The crank on my bike was bent and hitting the guide for back brakes. The back hydraulic brake was not working. I took it too the local bike shop but they did not have the appropriate tools to work with the brand of brakes on the bike.
All that being said, customer service has been very prompt and helpful to hopefully get my bike back on the road.

Powerful Bike

We recently purchased two Espin Nesta Bikes. There’s a lot to like about these bikes and of course a few things that could be improved.
Let’s start with the best features. These bikes have power. My wife and I ride together and there’s barely a difference in the bike response between our bikes even though I probably outweigh her by 100lbs. This thing can haul me up steep hills at close to top speed. I also was expecting my battery to wear down faster. So far this hasn’t happened. 20-25 mile rides and both bikes discharged at about the same rate. Again a pleasant surprise.
Some of the best features include the thumb activated throttle, this gives you complete use of the handgrips with no risk of accidental throttle. The stock seat is very comfortable. Thought for sure we’d be looking for an upgrade but the included seat is fine. The bike is very simple to use. Turn on the battery, power up the bike, choose a level and off you go. The “fat” tires are cool as they give lots of stability on and off road. While I wouldn’t go full tilt mountain biking on this model it handles off road trails, the beach, gravel roads and dirt roads really well. Ergonomically the bike is well designed and appears to be very well constructed. The bikes are outfitted with great shocks and disc brakes which make the riding experience just that much better.
Some areas for improvement. Yes it’s a folding bike but it is awkward to fold. A better more balanced stand to rest on would help a lot. The folding handlebars fold to the opposite side of the kickstand. This makes it impossible to use the kickstand with the handlebars folded down. The bike just topples over. In general the existing kickstand is too upright for reliable usage even when the handlebars are up. A moderate breeze will blow the bike over so I’m always looking for something to brace it against when parking it.
The display screen is a disappointment. The display itself needs to be brighter. It’s difficult to see it in daylight but the big issue is the screen itself. It’s plastic and is easily scratched. The first time we transported the bikes in a folded configuration one screen was badly scratched just from incidental contact. We’ve since fashioned covers for them but it’s too late for the one screen.
We originally ordered these bikes in December 2020 and didn’t actually receive them until late March 2021. I realize shipping and importing has been difficult. Just be aware that the delivery times promised on the web(at least in our case) are way off. One bike frame was scratched from shipping wear and tear. One bike was missing some hardware. Fortunately it was just nuts and bolts that were easily acquired at Lowe’s and the scratches are just cosmetic. The enclosed instructions aren’t very helpful and the online support is for other Espin models. There is not yet any on line video tutorials for this specific model. Overall we’re happy enough now that we have the bikes and we’re on the road.
