The wind rushes through your hair as you accelerate in silence past ordinary bikers. The crisp smell of the mountain air is all you think about as you use your new freedom bike to propel you to your destination. No sweat No hills to worry about just plain old fashioned fun! Bring a smile to your face with our 4000W gearless hub motor kit! The 4000W Kit version really kicks the fun and acceleration up a notch. We would venture to say this is the point where true high performance really begins! This 4000W system offers great hill climbing performance with either motor option. Conquer hills and terrain with confidence with this awesome 74V performance system.
At the heart of this kit is the custom HPC air cooled brushless motor. This motor now features an aluminum stator for better heat transfer and increased corrosion resistance. Not only that, but we were able to put in even higher grade laminations that allow for less cogging torque, easier pedaling, and 3-4% higher peak efficiency over last years motors! This gearless powerhouse of a motor also has extra robust 14mm axles to handle offroad abuse. We offer both a high torque version (Striker) and high speed version (Thunderbolt). See the table at the bottom of this page to compare motor systems and power levels.
This is a complete kit and includes everything you need to convert your bike into a fully functioning, high power e-bike!
Choosing a Power Package- Higher Wattage (W) means more power! The 2000W system utilizes a 52v battery system that can provide over 2.5 hp and can handle relatively steep grades. The 3000W and 4000W systems have over 4 and 5 hp respectively and the NEW 5000W system features a brand new wider stator with 5mm wider neodymium magnets and stator can deliver OVER 6.7 hp! ALL SYSTEMS ARE FOR OFFROAD USE ONLY ABOVE 750W! Please check your local laws and regulations. We can offer kits well over 5,000W but you will have to call us to discuss your specific build! Standard bike frames will not hold up past 5,000W!
Choosing a Battery- New batteries from HPC are a special Lithium based tri-metal blend of Nickel Manganese and Cobalt or Li-NMC for short. These batteries are 25% lighter than the outgoing LiFePo4 batteries and deliver consistantly higher voltages across the voltage range which translates into more speed and range. We employ custom HPC specific moulds and mixtures of our prismatic pouch cells in the Standard and HPC Elite NMC packs. These are proprietary performance cells from HPC and we do sell to OEM customers as well. We can also build ANY pack you can dream of using the latest Panasonic or Samsung high drain 18650's- just ask! If you want to build a 200+ mile range bike, it can be done, so let your imagination run wild! The standard battery is 11Ah. Optional 12.5Ah battery adds about 15%. The 13Ah HPC Elite pack provides our highest energy density battery with the lowest internal resistance and voltage sag. It is the ultimate battery for big power users.
Choosing a Charger- By default any battery system you purchase from us will come with a 2A Charger. This means that if you have a 10Ah battery system it will charge in about 5 hours. You can choose to upgrade to a 4A charger which is twice as fast and will charge in half the time (2.5 hours for a 10Ah pack). Finally the fastest charger we carry is a 6 Amp Charger which can charge in about 1.6 hours (or 3x as fast as the standard charger).
Choosing a Wheel Build- Choose the kit with the same size wheel as the bike you wish to convert. If you have a 26" bike you would like to convert then choose one of the 26" wheel options. Be sure to pick your preference of an all silver or all black wheel and the size. All of our wheel builds feature the best spokes (Sapim) you can find and very sturdy double walled aluminum rims. All wheels are hand built at our facility in Chatsworth, CA, and we use only Phil Wood spokes, cold rolled and cut on our Phil Wood spoke machine. Our wheel builders have 40+ years of combined wheel building experience.
Choosing a Throttle- This is totally up to the end user- It comes down to personal preference do you prefer a motorcycle type twist grip throttle or a thumb throttle? 95% of our bikes come with a twist throttle if your shifters are thumb throttles
Choosing a Freewheel- Choose the number of speeds on your freewheel based on the number of rear speeds on your bike. Most 21 speed bikes use a 7 speed freewheel 24 speed bikes use an 8 speed 27 speed bikes use a 9 speed freewheel and 30 speed bikes use a 10 speed freewheel.
Choosing a Rack/Bag system-We also offer our exclusive Frame Bag battery system. The frame bag allows a much more central weight balance These bags are hand made in the USA with exceptional attention to detail and make for an incredible ride! These new bags are waterproof, and fire retardant with nomex IIIA and kevlar on the inside. The bags feature lockable storage and hardshell sidewalls to protect from punctures. The huge upside is the huge battery capacity- on a frame with good clearance, a 100 mile range battery is possible!
If you prefer a bolt on rear rack, we can do that as well! A rear rack and bag system is a no cost option.
E-Bike Diagnostic Computer: The E-Bike Diagnostic computer is a very useful tool for your electric bike and is highly recommended. It delivers vital information about your electric kit at your fingertips such as: speed, distance traveled, battery level, and Efficiency (measured in Wh/mile). It also allows you to limit your power level to your desired level so you can save battery. With this computer you have the ability to make any kit street legal!

Your words are too kind, Cindy R. You're making us blush!
We started as a company selling only scooters and evolved into one featuring thousands of products. Check out our transition video.
With that being said, we know "all work and no play makes Jack a dull boy." We still uphold certain company traditions- our annual company hacky sack race, and adult tumbling classes (it's a team-building exercise!). Yup, those still exist.
