The Surge is the next phase in the evolution of our E.P.O. program. 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. 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 new 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.
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 (230x65) 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 Surge’s revised construction and shape is one of the biggest leaps forward over its predecessor, revisions to the front triangle in both construction and tubing profile have helped improve the bike's stiffness while still remaining compliant enough that the bike isn’t harsh, the new down tube is substantially slimmer and has a much more organic profile that the one that went before it.
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.
The final piece of the puzzle was to have a battery that was easily removable. Hearing of riders doing “double battery rides” is very much a reality and we wanted a system that allowed this to happen as easily as possible. The battery is now removable with the use of just a key, so there are no more bolts to undo and it should take a matter of seconds to swap. Second batteries will be available from Orange and will come with the protective cover as standard.
We've chosen to work with Shimano, using the E8000 pedal assist system. The features it offers work extremely well for us.
Due to the size of the drive unit, no change to bike geometry is necessary. The E-bike you see here is the exact same geometry as our Alpine 6 model.
The power is delivered when the rider starts pedalling. We've found with the Shimano E8000 unit the power is smooth and controllable, even in boost mode. This is crucial on the technical terrain we love to ride.
Unlike other drive units on the market, the Shimano E8000 crankset has the same Q-factor as the human powered cranks you are used to, this means no awkward changes to your pedalling position. This drive unit also has a zero-drag feature, so as you surge past the assisted power, often into descents, all of your pedal input goes into the drive, rather than dragging the motor's "gearbox". This gives a really responsive feel, when you're hitting those high-velocity descents. You soon forget you're riding an E-bike until the assist kicks in again to help power you up the next climb.
Here are the technical specifications of the Shimano E8000 drive unit.
All three support modes will assist until 16mph.

Please note: This is for guidance only. You may be taller or shorter, it doesn't mean our bikes will not fit you. The best way to determine the correct bike size for you is to try one. We've added some more explanation on sizing theory here: What size frame do I need?
We think the best way to find out what an Orange Bike really has to offer is to ride one. So don't just take our word for it, get out there and give one a go.
