Description

At Orange Bikes it’s all about the ride, and we’ve made substantial improvements to our e-bike chassis which deliver the most engaging trail feel, The 170mm travel Surge will take on the biggest terrain, and is not shy when is comes to sending those gaps. Excelling where the uplift doesn’t go. Some of the best trails lie beyond where your lift pass takes you – enter the Surge.

The second generation of the Surge E.P.O. model incorporates the new Shimano 8035 battery technology which has allowed us to revise of the ergonics of power assist controls – it’s one those little things that can feel like a big difference.

Big adventures and an e-bike with big ideas, way above the lift station. Fast and sure footed, the stability in the Surge’s geometry will give you confidence on any trail.

The updated Surge is a revelation and we urge you to try one. E-bikes can be a devisive topic, but once you are bitten by the bug they are hard to resist.

CONSTRUCTION:
Something that was painstakingly pored over was the suspension characteristic of the new Alpine 6, with everything we gained from that bike we wanted it to translate across into the Surge. Revisions have been made to the shock mounts to accommodate the new metric rear shock (230×65) and the increase in travel from 160 to 165mm, we have also focussed on increasing the amount of progression in the system which has seen a substantial increase, reduced the bike’s anti-squat value and decreased the amount of pedal kickback in the system.

The new Surge’s redesigned front triangle accomodates the new Shimano 8035 battery system in under an integrated battery cover within the reprofiled downtube. The profifle of the frame is now much more streamlined and the battery is easily removable for charging.

While the rear swingarm has taken cues from our 327 DH bike in its profile, this has been done to help deal with the large amounts of torque being produced by the motor, the additional overall weight of the bike and the fact that this bike acts like your own personal uplift vehicle where descents are the order of the day.
