The go-hub kit is the flagship top of the line electric bike conversion kit made by Crystalyte.
The go-hub kit is the ONLY conversion kit on the market that features a front mounted controller and NO EXTERNAL CONNECTIONS to plug in except for the battery power wire.
This is the only kit on the market that is "ready to run" right out of the box!!
Simply install the motor on your front fork, the throttle on your handlebars, the rear rack with battery and run just ONE wire from the front controller to the rear battery and plug it in.
That's it. Your done!! Turn the key on and ride your new electric bike!!
Our trike kit is also "ready to run" out of the box
We designed the go-hubTM kits to be the best quality and easiest to install conversion kits available.
The designs of the go-hubTM kits are manufactured by Crystalyte exclusivly for Largo Scooters and these kits are only available through us or one of our many authorized reputable go-hubTM dealers.

Our lower profile trunk/battery bag expands for more room. The go-hubTM low profile trunk attaches to the rack with velcro straps that are attached to the trunk. The go-hubTM trunk has an expandable top to hold the 2 amp charger. The low profile go-hubTM trunk comes standard with the 24" go-hubTM trike kit. The low profile go-hubTM trunk features a built in key switch, charger/accessory expandable top, side handle, reflective safety strips, and velcro straps. Charging is done using the same Anderson connector that is used for the main power to the controller. When charging with this bag the key must be in the ON position.

Notice in the photo that there are no external connectors or excess wires to deal with!! Installation is a simple matter of removing your bikes front wheel, tire and tube. Mount your tire and tube onto the go-hubTM wheel then mount the new wheel onto your front fork.
Before you order check your bike for the following front fork measurments: The fork must be rigid and made of steel (chromoly is the strongest) and must be at least 3.75" wide at the dropouts (where the wheel bolts on) and 3" wide between the forks 4" up from the dropouts for motor clearance. The shaft/axle of the motor is a standard 10mm so the dropout holes MUST be this wide to fit the axle of the motor. Note: If you are un-sure of your bikes measurements please call.
Customers who return kits due to improper fork clearances will be charged all shipping costs.
Mount the thumb throttle to the handlebars and clamp or wire tie on the electronic controller to the front of the steering tube (26" and 700cc kits). By mounting the controller onto the front of the bike this allows for better cooling and a neater look. The 24" Trike kits need to have the controller mounted to the rear seat tube.
Mount the Topeak rear rack and slide the Topeak EX Trunk battery pack onto it. For a lower profile battery trunk order the kit with the go-hubTM low profile trunk that velcros onto the rack.
Run the power wire from the controller back to the trunk, plug it in and you are done!! Carry your charger with you and charge your batteries anywhere just by plugging the charger into the batteries and taking the AC wire out of the trunk and plugging in!!
The go-hubTM Kit comes "ready ro run" out of the box with all of the components connected inside of the controller which makes installation very quick, neat and easy with no messy looking external connectors or excess wires.
The only connection that you need to make is for the battery!!
You are now ready to experience the fast silent ride of your new go-hubTM electric bike or trike!!

go-hubTM Motor Technology
The go-hubTM motor has three phases, or power supply wires (think of this as a 3-cyclinder automobile engine.) Each of these phases fires in succession with the others, determined by the "Central Brain", or what is called the "PWM (pulse width modulation) Controller." Inside the motor on the outer perimeter there are many "rare earth magnets".
Closer to the center of the motor are the wire coils, also wired in three phases. As a pulse of electricity is sent to the motor from the controller the coils create a strong magnetic field, which repulses them from the magnets and causes the motor to advance (rotate) away from the magnets. The controller then sends another pulse of electricity and the next phase fires, rotating the motor even further. It's helpful to think of our automobile engine example: 3 cyclinders - each firing one after the other.
There are three power (phase) wires going into the hub motor, and five Hall Effects Sensor wires coming out of the hub motor. The Hall Effects wires are used only to help the motor start from a dead stop.
The go-hubTM motor is brushless so there are no brushes to wear out as in a brushed motor.
Since there are no parts touching each other inside of the motor it runs virtually smooth and silent!!
