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

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?

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.

Worth the wait

I ordered the Flow for my wife in August and it did not get delivered until November. Thankfully, we live in the South and she was able to get out and ride for a bit before it got too cold out. She loves her bike and she doesn't know what she would do without it. I'm so glad that we discovered Espin. I'm ordering a Sport for myself. I can't wait until Spring!!!

2 flow review

You definitely need a comprehensive owner's manual. The Chinese version is insufficient. Other than a broken tail light on one of the bikes, the 2 Flows are just great.

As expected

I ordered our first two bikes (1 Sport and 1 Flow) in October for November delivery. Actual delivery date was February 2. I had watched several assembly videos on YouTube so I knew what to expect. Both went together very well with no problems. Packaging was extremely well done. I had done a lot of research in preparation for my purchase, evaluating features, pricing, and others' results before deciding on espin. My first ride was a hoot; 37 degrees, but it was worth it. Oh yes, I'm 74 years old, and my wife 73. Price to value was good, but I can save you $$ if you email frosty9001@aol.com, and show espin savings in the subject line. I'll email you a savings link back with a code. So, my only issue was delayed delivery, so order now for spring delivery.

Good rides!

Wife and I both have new Flows. Only have 20 mi on them due to
Poor weather. Great bikes, easy to assemble. We are both seniors so I replaced the seats for more comfort.
