We've been closely watching e-bike components maturing since the very first prototypes. Our first thought was, if we're going to do this we need to build what we would call a proper bike not a 'concept' piece for the show halls but a working, useable mountain bike for the terrain we ride. The E.P.O. program was born.
Working with Shimano we based our design around the E-8000 pedal assist drive. We like so many features of this unit. Standard MTB pedal Q-factor, zero drag and most importantly the fact that we do not have to compromise our geometry. The Alpine 6 E rides much like a standard Alpine 6, with extra ‘Vroooom’ on the ascents. We added 20mm to the wheelbase to keep the front down when climbing under power and to give more stability at speed.
The resulting bikes have been a revelation. Every test rider has come back raving about their experience on the bike and how it will bring a major new way of thinking for the sport.
We just love where e-biking is going and we think the Alpine 6 E is a benchmark in that progression. We think you will too.
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.
