eBikes might be good for commuters who don't want to arrive at work trailing a river of sweat, but the technology can also provide a helping hand – or foot – to cyclists who want to get down and dirty. Shimano has recognized this with the new STePS MTB, a rugged eBike motor designed for off-road performance.

Just like the STePS system it launched last year, Shimano's MTB motor is a pedal assist system that augments the power put into the pedals by the rider. Once you reach a certain speed, the assistance cuts out.

That means the electric assistance isn't designed to create a new generation of rider hitting incredible speeds on mountain bike trails. Instead, it's designed to give a gentle boost to enthusiasts who aren't quite in peak physical condition.

Power by compact 500 Wh battery, the electric motor delivers 70-Nm (52-ft.lb) of torque and is impact-, vibration- and water-resistant to handle the rigors of off-road riding. Riders are able to control the system through a handlebar-mounted computer similar to the Di2's display, and there are three different drive modes available: Eco, Trail and Boost.

The motor is coupled with a dedicated 34T or 38T chainring, but beyond that it's up to you whether you pair it with Shimano's high-end XT and XTR electric components or the brand's mechanical 10 and 11 speed drivetrains.

According to Shimano, the distance between the outside of STePS MTB's crank arms (or Q-factor) is the same 175 mm (6.9 in) as on regular chainsets, which means it should feel natural to ride on tight trails.

The system launches in October 2016.

Lets be very careful here...bike + motor = motorbike....not mountain bike. We need to keep the distinction clear so we don't further complicate trail access efforts.

Screw that! This is not an add-on, the bike was to be made to fit this contraption, no thanks...
