Our take on the Polygon Siskiu TE-N Bosch E-Mountain Bike

The Siskiu TE-N is Polygon's all-mountain electric mountain bike built around a Bosch Performance Line CX motor with 85 Nm and a 625 Wh PowerTube battery. It pairs 150 mm front and 140 mm rear travel from RockShox Lyrik Select and Super Deluxe Select+ suspension with Magura MT7 four-piston brakes and 203 mm rotors. That is serious trail hardware for the money, though it is a heavy, full-power e-MTB rather than a light trail bike. Riders who want Bosch reliability and long-travel capability in one package will find it a strong value against premium-brand e-MTBs with similar spec.

Pros
