STATE OF THE ART MOUNTAIN BIKE TECHNOLOGY
We take top of the class gravity mountain bikes made by Santa Cruz and seamlessly add our own industry leading electric drive system.
There are no performance compromises by having to alter the frames to fit the drive system like other e-mtb's. The award winning ride feel is preserved.
Industry leading metrics define the Kranked E² Superdrive. A compact, modular drive system that outputs
2250 WATTS PEAK
750 WATTS NOMINAL
170 n/M TORQUE
We didn't call it the E² Superdrive without good reason.
MODULAR, FUTURE PROOF
Easy to remove, service and upgrade.
Each part - the motor, controller, gearing, throttle, crankset and bracket is modular and easily serviced and upgraded when needed. There is no planned obsolescence.
Take it off and one is left with a high end mountain bike, put it on and you have a high performance electric bike.
100% RIDER CONTROL
Rider decides when and how much power assist the bike receives at every moment.
There are no microprocessors controlling the power input. No crazy 'pedelec' that only allows power when pedalling. Who thought that was a good idea? It's a terrible idea.
100% rider throttle control. You control your ride.
An integrated fan on the belt drive circulates air through the E² Superdrive.
The motor is thus cooled internally and externally through the custom heat sink.
This allows the system to run way beyond it's nominal rating into the zone we call peak output.
Not that anyone plans to accelerate up mountains, right! Well just in case, we got you covered.
By keeping the battery in a backpack the weight is neutralized off of the bike.
This allows for a lighter, more responsive handling bike without an awkwardly placed battery upsetting the balance of the bike.
The battery plug has a built in spring that keeps a solid connection but releases when you and the bike go in separate directions.
The E² Superdrive is optimized to deliver power to match a 100 pedal stroke cadence.
This allows meaningful pedal input in every gear. The 1 by 11 rear cog set is driven by a 38 tooth front ring.
This gearing is really important to preserving the ride feel and handling of the bike as the native balance points of riding demand pedal input.
There is nothing better than pedalling in a big gear straight up a massive mountain!
Our freewheeling crankset allows unlimited ride options.
1) Ride with no electric assist - that's right! Lots of time on the trail you are flowing beautifully and there is no need for extra power.
2) Ride with a combination of pedal input and E² Superdrive input. How much of each is flexible at every moment. It constantly changes depending on the terrain etc.
3) Ride Moto style with no pedalling. Maybe the trail is too technical to throw pedal strokes, maybe you are too tired, maybe you just don't like to pedal. No problems, the E² Superdrive has you covered.
BUILT TO LAST
Made in Canada with real materials.
Engineered to output industry leading wattage and torque. No plastic gears like the other systems. In fact our planetary gears need to go through an extra hardening process.
Made to withstand all weather and trail conditions.
Made to take you to places you have only ever dreamed of, in a manner that will put a massive sh!t eating grin on your mug!
THE REAL DEAL
Don't mind our gentle ribbing of our competition at the beginning!
The E² Superdrive spools up pretty good. Since you've made it this far into our features page we thought you'd appreciate seeing the belt reduction module spooling up to 7000 rpm.
Not suitable for your kitchen, right!
Tell me the folks trying the Kranked Bikes here aren't having a super fun time!?
Besides all the cool technical stuff above that we've done, the ultimate goal is to get you outside into nature in a super fun, ecological, healthy way.
It's eco-tech that will make you smile, ride after ride, after ride.
Ride hard, ride free! and have super fun!
