Key featuresexpand_more

Based on Polygon’s popular Siskiu range of trail bikes, the T7E applies the same doctrine of building amazing bikes with shockingly reasonable price tags, to ebikes. Powered by you and a lightweight mid-mounted Shimano motor, the T7E turns unavoidable ascents into white-knuckle fun! The T7E has a higher capacity battery than the T6E for improved range, and the drivetrain is upgraded to a 1x12 Shimano SLX arrangement, offering even smoother shifting.

SR Suntour makes great bike suspension, the T7E’s Aion and TriAir2 Shock are the pick of the range. Smooth with great progression, this suspension fork and shock combination will give years of supple shock absorption. The Flip Chip is a useful little gadget that allows you to switch the rear wheel from 29-inch to 27.5-inch, changing the character of the bike... if you want to.

Putting all that power down on the trail requires a good tyre, the T7E’s Hans Dampf, by German manufacturer Schwalbe, is one of the best Enduro tyres on the market. The tyre’s Speedgrip compound delivers fantastic grip on a broad range of surfaces and the highest level of puncture protection. Stopping the bike are a pair of SRAM Code R brakes paired with big 203mm Shimano discs, a powerful combination that makes the most of the Code R’s four piston calipers. Rounding off the package is a hydraulic actioned dropper post.

Ride for longer or squeeze more climbs, descents, berms, jumps and good times into your rides with the T7E ebike. It’s the trail bike of your dreams without a price that causes nightmares.
