Polygon’s Siskiu mountain bike range has earned itself a reputation for great riding bikes and unbeatable value for money. Now Polygon is turning its attention to ebikes and applying the same winning formula. The end result is a selection of mind-blowing electric mountain bikes that give much more expensive bikes a run for their money. The Siskiu T6E is the most accessible bike in the range and more than enough bike to take on the UK’s most challenging trails.

The Siskiu T6E is equipped with a mid-mounted Shimano DU-EP600 motor and a 504Wh battery that is integrated within the bike’s downtube. The mid-mounted engine keeps this bike’s weight low and central; the bike’s stable character is emphasised by its slack geometry and fast rolling 29-inch wheels. The motor delivers 85Nm of torque to the Shimano Deore drivetrain, allowing you to make use of the ten gears to climb steep trails quickly, with minimum effort. The pedal assist power kicks in when you need a boost allowing you to ride at speeds of up to 25kph on trails that would otherwise require a low gear and plenty of puff.

Suspension is provided by a SR Suntour Zeron fork and Edge Plus RC shock: 140mm of suspension travel is just right for burning rubber down the UK’s most thrilling trails. The suspension has plenty of adjustability to make it simple to find the right mix of damping and rebound. Schwalbe Hans Dampf tyres and SRAM Code R brakes, a dream combo for controlling speed down wild terrain, round-off this amazing ebike package.
