Off-Road Electric Bikes


The HPC Revolution is our premier product here at Hi-Power Cycles.

What you see here is a product that has been over two years and five prototypes in the making.  No costs were spared in making the ultimate Freeride/DH electric bike on the market. The Revolution is hand welded and 100% built here in the United States. It is designed to be the fastest, most nimble, lightest weight and most powerful downhill electric bike available anywhere. It all started with a hand-built 6061-T6 Aluminum frame that is hand welded one at a time by a highly esteemed Aerospace welder here in Los Angeles, CA.

Our group of engineers for this project are experts in bicycle and moto geometry, as well as suspension performance. This amount of R&D, lab and field testing, and suspension tuning puts the Revolution head and shoulders above its competition.  There is not one off the shelf part for this frame, all parts- including bottom bracket, head-tube, swing-arm, shock mounts, seat tube, etc. are made from CNC Aluminum in small batch orders. At only 12.8 lbs, the Revolution frame is the lightest of its type in the industry! We are beyond proud to build this bike from scratch here in the USA. 


The Revolution X is our flagship model and takes the Revolution to the pinnacle of performance.  Suspension and Braking are out of this world! The Revolution X comes standard with 203mm travel Rockshox Boxxer World Cup Fork which is widely regarded as the best DH fork money can buy. The standard Vivid R2C Air shock provides over 9" of frame travel! Together, these suspension upgrades not only perform better than the standard suspension, but save nearly 2 lbs of weight as well! The highly regarded Schlumpf High Speed Drive that allows for a 85T equivalent front chain ring and pedaling beyond 50 mph with the click of your heel. Possibly the most jaw dropping performance item of the Revolution X is the standard Magura MT7 quad piston performance brakes.  They literally blew away the competition in terms of braking performance during initial testing to see which brakes would power our mighty Revolution X.  The sheer braking performance is truly astounding.

The Revolution X also offers up unheard of power levels with 5,000W as standard with an option for a staggering 6,000W machine capable of up to 60 mph. These Revolution X units are not for the faint of heart and offer extreme performance in nearly all conditions.

We urge you to swing a leg over the Revolution and test ride one at your local HPC Dealer.  You will then understand our labor of love, and why the Revolution is such a spectacular machine.  The ride and handling are truly second to none!
