Gives Your Daily Commutes And Cruises A Smooth Boost

The fine-tuned Espin motor and controller that have undergone rigorous testing and QA is powerful and reliable. The Samsung 653 wh battery is fully integrated in the lower part of the frame for weight distribution and can take you as far as 50 miles per charge.

Hop On And Off With Ease

This step-thru bike was meant to work particularly well for urban commuters. It can easily maneuver city streets, and you can get on and off the bike quickly and easily to help keep you safe. Like the 21 Nesta, it’s great for shorter riders with a low step-thru frame. Also, it has 8 gears, a max speed of 20 mph and will work well on any terrain. So, you can ride the bike outside of the city as well.

Your Safety Matters

You should never have to compromise on safety or quality. Espin delivers both, with best-in-class manufacturing, great design, and quality performance-all at an unbeatable price point.

  1. Love my eBike. The only issue is the back brake. The brake is weak and I have to pump the brake handle. I was told I need to take it to a bike store and have the brakes bled. Our friends also bought a sport and a flow and we also have a flow and all 4 bikes have the same breaking issue. The breaks still work I just wish they were a little stronger.

  2. I am pleased with the quality and performance of my new bike. There are several things that I think could be improved upon: The seat is very uncomfortable, it is too hard and too small. I will probable order a different seat. The display cannot be read in bright sunlight even with the brightness all the way up. I would prefer a twist grip throttle as I have trouble holdi ng a constant speed with the lever.

  3. 2020 Flow
    I have the 2020 Flow. It is an attractive bike and has plenty of power for getting up hills. There’s a bit of a jump when you start peddling but I think that was resolved on the 2021 version. I put slime in the tires to try to avoid the issues with flats and so far so good. I ride on some dirt roads, mostly asphalt and the chunky tires are perfect. I have panniers and I can pick up mail, groceries etc. easily! I have a blast zooming around on my Flow and don’t usually use more than 1 or 2 PAS because I am trying to get some exercise too! Only real complaint is the seat, it’s pretty uncomfortable…I will replace it one of these days. I have had zero issues with the bike — it’s the bomb!

  4. A Joy To Ride My Espin
    Received my first ebike, an Espin Flow a month ago. No issues with assembly. Chose to replace seat and added mirrors and bell. Chose this ebike based on reviews, appearance and design. Even though it is a step through version it is challenging to get on and going (I’m 5’4” and 61 y.o..). I am up for the challenge, though, and having fun tackling hills. Thanks.

  5. This bike is beyond awesome!! I got the green 21Flow and it rocks! The battery lasted all week before I had to charge it, and I rode every day. I also dig how it comes with a back rack. If you are going to get an e-bike, get this one. 5 different pedal assists, a throttle, just friggin awesome. Money well spent!
