SISKIU HE PURPLE (WITH BOSCH)
Polygon
Trail
SISKIU HE PURPLE (WITH BOSCH) is an alloy electric trail mountain bike (2024), from Polygon, part of the Siskiu family. This setup will suit riders looking for a balanced off-road setup, leaning toward a balanced riding position, while being well suited to natural trails and mixed off-road terrain. On MatchBikes metrics, it scores well for a comfort-leaning ride feel over longer rides, capable suspension support for rougher terrain, and all-round climbing capability rather than a narrow specialty. The main trade-off is less emphasis on outright speed than speed-focused builds and battery range that is better for shorter daily use than long all-day outings. This summary is a starting point—compare this bike on MatchBikes.com with similar bikes.
