Largo Scooters introduced the new
CRYSTALYTE go-hubTM motor kits, bikes and trikes in 2004.
We are the exclusive worldwide go-hubTM distributer and have designed these kits for ease of installation and top performance using the best quality components available.
Our new 2011 CRYSTALYTE go-hubTM electric hub motor bike kits offer you the very best value and performance in the world today!!
Our new 2011 kits feature heavy alloy rims with heavy gauge stainless steel spokes.
We have designed these kits to be a huge improvement over any of the competitions electric bike conversion kits.
There are NO EXTERNAL CONNECTORS on the go-hubTM kit. Every other brand kit on the market uses external connectors which are prone to failure. The CRYSTALYTE go-hubTM also uses a BRUSHLESS MOTOR. Other brands use a BRUSHED motor which is not as efficient or quiet and will also need the brushes replaced eventually which involves dismantling the entire wheel!
The top of the line CRYSTALYTE go-hubTM kits are the best conversion kits in the business HANDS DOWN!!
The main component of our 2011 26" CRYSTALYTE go-hubTM conversion kits is the 600 watt (750 watt peak) Crystalyte #408 brushless, gearless, silent hub motor. This motor has no moving parts. The motor itself spins around the center shaft/axle. Max rider weight 250 lbs.
The 24" CRYSTALYTE go-hubTM trike kits use a Crystalyte #409 motor which has slightly less speed but has more torque to handle the extra weight of a trike. Max rider weight 300 lbs.
The go-hubTM CRYSTALYTE motor is a direct drive motor and is virtually silent!!
All you will hear is the rush of the wind.
Shipping weight kit: 25 lbs. 5 oz.
Shipping weight batteries, charger and trunk: 32 lbs.
Weight of kit installed on bike: 47 lbs. 12 oz. (32 lbs. batteries,trunk charger and 15 lbs. 12 oz. for the rim, spokes, motor, controller and throttle).

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!!

Customer Feedback

"Hello Danny!! I installed the go-hub motor kit today. It runs like a dream! I bought a Roadmaster 26' from Walmart for $53.00, and the go-hub System fits Perfect! Eventually I intend to swap the tires for a decent road tire. When I took my first ride, the looks from people working on their lawns was funny as heck. I'm cruising along in about 14th gear with minimal pedaling, and the puzzled looks on peoples faces was a real riot. I could see the "How the Heck is he going so fast" look lol!! I live in the country about 12 miles from work, and actually am writing this letter from work. I rode my bike with the go-hub System to work in 22 mins. This ride would normally take about 8 mins in my car, but the advantage of fresh air, a little exercise, and 5 cents to recharge the batteries sure does beat paying 2 bucks a gallon for gas. I assure you my high praise for the go-hub System will be heard by many in my area. The go-hub is Awesome!
Thanks again Danny for all your support and endless tolerance to all my questions on the phone. Your professionalism is most admired and your product is a solid winner. Thanks for the great communication and dedication to your customers. You've got my respect Sir!
Good Luck to you and thanks a Million!! Michael, Pa."

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!!
