The ergonomic ErgonGS1 grips give a comfortable, safe locked grip for long distance riding, followed by hydraulic adjustable brake levers which activate rear lights and regenerative braking when applied.

Help & Advice

There are usually two key types of frame. However, certain brands have slightly different names for them so keep your eye out!

Step Over vs Step Through

Sport - (Step Over) 

Sport models will usually have a high tube at the top, in front of the seat. This will usually require you to lean the bike slightly to mount your leg “over” the bike. Sometimes bikes will also be called Diamond, or Gents bikes. 

Comfort - (Step Through)

Comfort were traditionally known as “Ladies” bicycles, and in some cases this naming convention has carried through. However, all it tends to signify is a lower top tube. By far the majority of electric bikes are step through because they're so easy to get on and off.
