ePAS, or Electric Pedal Assistance System, is the magic behind modern eBikes and the major design change from the old electric bikes. Rather than using a motor to drive the wheels directly, ePAS uses a modern light weight Motor to make the action of pedalling easier, in much the way as a change of gear would do.

This approach means that not only do bike have much better range, but the user has a much closer experience to un-powered cycling, which is much more attractive to most cyclists. As a result modern eBikes are being considered as a credible addition to any self-respecting cyclists fleet of machines.

So how does an ePAS system actually work?

The secret to ePAS systems rely in 2 components. The motor that powers the crank and a computer that controls the power in the motor. Once the users starts to pedal, the computer measures the power output and instructs the motor to assist the users in a full rotation of the cranks. The user has a control on the handlebar to control how much of a boost is provided, from gentle assist through to full turbo mode.

For the user they feel a sensation of ease as they push the pedals, making it ideal when cycling uphill, or towards the end of a long ride. This makes the bikes ideal for cyclists of all ages, from older cyclists looking for a more pleasurable experience on a leisurely Sunday right, through to mountain bike riders who want some assistance on the up hills before switching the power off for a descent as well as commuters looking for a bit of assistance in pulling away from traffic in city centres.

Obviously the trade-off of using high power mode is the drain on the battery which means a shorter range between charges although cyclists should expect around about 45 kilometers of range of a fully charged battery.
