You appreciate a graceful step-through frame that allows you to easily, safely mount and dismount your e-bike anytime you want. You and Flow are going to get on so very fine.

So far so good

My first e bike. I'm getting familiar with how to use both the gears and pedal assist.
I'm pleased with the ride and looks of the bike.
I do need to have the rear brake checked. I assume it needs more fluid.

Meet Flow 




Take it easy 

The 21 Flow features cruiser-style handlebars so you take a relaxed sitting posture when you ride about town and soak in the scenery.  

No need to be hunched over 




Hop on and off with ease 

Riding a bike can help people stay fit and feel younger. It's also low impact, so it's pretty easy on the joints, especially on a step-thru bike. Step-thru bikes allow for a more relaxed sitting posture due to the easier placement of cruiser-style handlebars as well as the often more forward placement of the pedals. This more natural sitting posture puts a lot less strain on the joints, and this makes it a popular choice for senior riders.










The e-bike for everybody

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 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.
