Orange Surge RS 2019 - Electric Mountain Bike

The Orange Surge RS 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, confident handling and 'pop' that you'll find in a long travel e-bike.

Key Features:

• 6061 alloy frame with Alpine 6 Geometry
• RockShox Lyrik RC2 fork offers 170mm of travel
• SRAM XO1/GX1 Eagle 12 speed drivetrain for reliable gear shifting
• SRAM Guide RE hydraulic disc brakes
• Sizes: Medium, Large, X Large
• Colour: Fizzy Orange

Drive Information:

• Motor: Shimano Steps E8000, 70Nm
• Battery: Shimano Li-ion 504Wh, integrated
• User Interface/Remote: Shimano Steps E8000
• Connectivity: Bluetooth smart phone and PC app

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 (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.

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 ithey are hard to resist.

Drive Unit:
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.

Highlights:

Pedal Assist Modes:
All three support modes will assist until 16mph.

ECO - Riding support while enabling maximum range
TRAIL - Gradual support for encouraging sportive riding
BOOST - Full support for maximum boost and uncompromised climbing
WALK ASSIST - As additional mode, walk assist can be easily enabled with the assist switch

Compact Concept:
Short chainstays (shorter chainstay length ensuring better manoeuvrability)
Narrow Q-factor of 177mm (compact and lightweight design for better handling with same Q-factor as current Shimano XT)

Performance:
Maximum power: 500 W
Nominal power: 250 W
Maximum torque: 70 Nm

LI-ION Battery:
Integrated version (504Wh)
Charging: 80% after 2,5 hrs / 5 hrs from 0 to 100%
Battery life: 1,000 cycles
