Who is this for?

Best suited to

Private land and farm riders who want an all-wheel-drive dual suspension fat bike at a lower price than the Series 5.

Consider alternatives if

You want to ride on roads or paths, where the road-compliant ACE PRO is the legal choice.

Standout strength

Two Bafang hub motors (95Nm each), a 52V 25Ah battery, dual suspension and 203mm 4-piston brakes, 500 dollars under the Series 5 RRP on sale.

Check before buying: Be clear on where you will ride it. On public roads it would be treated as an unregistered motor vehicle.
