The Bike Boost 36V/350W Complete System offers the ultimate electric bicycle conversion solution. The complete system has everything you need "out of the box" to convert your conventional bike into a high-quality electric bike. Complete System includes the Bike Boost Conversion Kit plus the Bike Boost Lithium Polymer, LiFePo4 or SLA battery & charger (if ordered). This manual covers complete systems, and conversion kits. A more extensive manual concerning batteries can be found at the following link:
The Bike Boost electric bicycle motor kit is supplied as a set of do-it-yourself parts for the user to install on their bicycle. Because this kit is installed, maintained and operated by the purchaser, NYCeWheels disclaims any responsibility for injury, damage or other consequences arising from the use of this product. Each installation will be different and therefore it is the responsibility of the purchaser to determine the best way to install the kit on their particular bicycle. The following instructions should be considered as general guidelines only - your installation will be slightly different. If you do not have the mechanical ability to correctly and safely install this kit, you should obtain the services of a professional bicycle shop or other qualified technician. Installation and use of this kit will create a vehicle that has exposed moving parts, electrical connections and high powered batteries.
Any or all of these components can be dangerous.
Federal Law mandates that no person under the age of 16 shall operate a motorized bicycle. Always wear a helmet, ride responsibly and observe all Federal, State and Local laws.
In some instances the charger may ship with the battery or with the conversion kit.

Motor: Direct Drive Brushless Hub Motor Power: 36v (350w / 20MPH) Wheel: Hand-Built with 350 Watt Brushless Hub Motor Rim: Flat Profile Double-Walled Spokes: 13 Gauge Stainless Steel Weight: 14 Pounds Hub Width: 85mm / 3.35 Inches (requires standard 100mm width between fork dropouts) Range: Range is dependent on battery capacity, weight of rider, route and pedaling.
IMPORTANT: You MUST only install a front hub motor on a bike with steel forks. NO ALLOY FORKS.
Alloy forks are NOT strong enough to support a hub motor. During installation and even worse during a ride, alloy forks can crack or break under the pressure of a wheel with a hub motor. It is important to tighten front wheels extremely tight when installing a hub motor and there is a strong likelihood of cracking alloy forks during installation. This could also be very dangerous if it happens while you are riding. Use your torque arms to eliminate the possibility of losing a wheel while riding and use steel forks to ensure your own safety. If you are unsure if your fork set is alloy or steel, test the fork with a magnet to ensure it's made of steel. If the magnet is NOT attracted to your fork it is an alloy fork and NOT steel. Replace your fork with a steel fork or find another bike with a steel fork to convert. NYCeWheels is not responsible for damages or injuries as a result of installing a Bike Boost hub motor on alloy forks.
The Bike Boost electric bike conversion system is universal and can be used to convert most conventional bicycles. However, there are a few criteria which must be met first.
Your front forks or rear dropouts need to be wide enough to accept the hub motor.
Front forks MUST be at least 100mm at the dropouts (where the axle fits into the forks). Rear conversions require 135mm of space between the rear dropouts (this is standard for most bicycles)
For front wheel conversion your bike MUST have steel forks.
The motor is very strong and there is a lot of torsional pressure at the axle. Aluminum is not meant to handle this kind of pressure and can crack. If your bike does NOT have steel forks and you want to convert using a from wheel hub motor, you MUST replace your forks with steel forks or consider finding another bike for conversion. Aluminum frames are suitable for rear wheel conversion.
Helpful Tip: To test if your forks are steel, use a magnet. If the magnet sticks to the forks they are steel and you are fine to install a front hub motor kit.
You MUST use a Universal Torque Arm.
A universal torque arm is included with every Bike Boost. Torque arms provide increased support at the axle and are used to prevent the axle from ever "spinning out" inside the dropouts. Both from and rear wheel conversions require torque arms.
NYCeWheels is not responsible for damages or injuries as a result of installing an Bike Boost hub motor on alloy forks.
Take the Bike Boost hub motor wheel and place it between the forks to make sure it fits correctly. After making sure it fits you can secure the rim in place. Make sure you secure the bolts tightly and secure a universal torque arm to keep the motor from spinning within the fork. If you apply power and the axle is not secured tightly, the motor will try to turn inside the dropouts, permanently damaging the wires connecting the motor.
Torque arms should always be used. Tighten axle bolts and secure torque arm. Inflate the tire, secure the brakes and flip the bike back over. Re-install and adjust the brakes. Odds are good that the new rim and old rim are not 100% the same, so adjust the brake pads so that they engage the rim with full contact. Adjust the cable for enough free-play to keep the shoes off the wheel during rotation. Electric bikes require more attention and care to brakes since you will normally be riding at higher speeds..
Next remove the grips from the handle bars to replace the brakes and install the throttle. The Bike Boost includes two brake handles with internal magnetic switches that cutoff power and deactivate the throttle when braking. You will need to connect your existing caliper brake inner-wires to the Bike Boost brake handles. After installing the brakes, install and connect the throttle. If you have a twist throttle, simply slide it onto you right side handlebar and tighten in place with the provided 3 mm hex wrench. If you are using a thumb throttle you will need to remove your right grip, slide the thumb throttle onto the handlebar, slide your right handle grip back into place and then secure the thumb throttle with the hex wrench.
It is a little different for each bike, but generally when installing a rear rack you'll use the axle for the lower support and the seat post for the upper support. If you are using the Bike Boost 36v LiFePo4 battery pack it will come with a mounting plate that can be secured to your rack allowing you to easily slide your battery on and off and lock it in place when riding. Racks come in many styles so each installation will be different depending on the type of rack used. Make sure your battery is secure and snug so it will not move when riding. If you are unsure about how to secure the battery properly you should consult NYCeWheels technical support.
Now you have to decide where you would like to mount the controller. The most common places are behind the seat or on top of the battery bag. Be sure to keep the controller in a well ventilated spot to prevent overheating.
For a clean install, route all of the wires toward the back of the bike and secure the wires with zip ties (included with the Bike Boost). Make sure you have full range of motion with the handlebars when tying back the wires and leave some slack at each zip tie.
Connect the wires from the motor, brakes and throttle to the controller. The connectors from each component will only fit to the correct mate on the controller. Please consult the wiring diagram for further clarification. Please note that there is a black & white "European Suppressor Loop Wire" on the controller that limits power to the motor to 200 watts when connected. This will limit the top speed of the motor to approximately 200 watts(14 MPH). Simply disconnect the loop to enable full power and higher top speeds.
When all connections are correctly and securely attached, plug your battery into the controller. If you're using your own battery and not the Bike Boost 36v LiFePo4 battery pack, you can use the wiring harness (included with the kit) to easily connect your battery pack.
Make sure the brakes are placed and tightened to your comfort level. Finally, make sure the brakes are adjusted, gears are tuned and everything is ready to go. That's it! Now you're ready to ride. Be careful and take it slow until you get the feel. Ride for a few miles and then come back to check everything over. Give the bolts a good tightening one more time. You should check all the components often to make sure all connections are secure, especially near the hub and at the motor.

NOTE: Damaged caused by water, dropping or any collision is NOT covered
Battery warranties vary depending on the type and capacity. For more detailed information about battery warranty, visit the following page:
Bike Boost Battery Warranty
"Spin Out" - Spinning out the axles inside of your dropouts - We are unable to be there when the kit is installed so it is up to you to understand the high torque involved at the dropouts and install them correctly. If your dropouts are not correctly suited to fit the axle then you should not install the kit on those forks. Get new forks, file the forks to the axle fit "flush" or contact us to return the kit. We will not refund or replace a motor that has been "spun out".
"Over Voltage" - Connecting a larger battery larger than 36 volts can damage the controller, wires and/or connectors. Damaging any kit component or motor by connecting the wrong battery type is not covered under our warranty. The Bike Boost controller will work with any 36 volt battery pack. Using the controller with any battery larger than this will void the warranty for your controller.
Water Damage to the Battery/Improperly Caring for the Battery - The battery warranty does not include damage from power surges, use of improper charger, improper maintenance or other such misuse, or normal wear. Bike Boost battery packs are 99% water resistant and fine in the rain but should NEVER be submerged in liquid.
* LiFePO4 Batteries need to be stored fully charged and kept in a dry environment.
* Batteries should not be submerged in liquid for any reason.
