How the Light Bee X drive works
A toothed belt takes power from the motor to the jackshaft, and a 420 chain takes it from the jackshaft to the rear wheel. Work out which stage is worn and you know which part to order.
- Belt stage: the OEM drive belt, the reinforced drive belt that stretches less, the front motor pulley and the primary drive pulley. A belt guard keeps sand off the belt.
- Belt replacement: the Primary Chain Kit 420 swaps belt and pulleys for a 420 chain on 13T and 30T steel sprockets. The ratio stays factory, and the chain copes better with sand, mud and an upgraded controller.
- Jackshaft: the genuine primary drive assembly, the lower jackshaft axle and the centre part with pre-pressed bearings.
- Final drive: the 14T front sprocket, the FabiRide 7075-T6 rear sprocket, 112-link O-ring and X-ring 420 chains and a master link.
Gearing and chain choice
More teeth on the rear sprocket give harder pull out of corners, fewer teeth a higher top speed. The O-ring chain keeps its grease inside sealed links and runs quietly; the X-ring chain adds lower friction and slower stretch. The master link lets you open the chain for cleaning or a sprocket swap without a riveting tool.
Suspension
For riders who have outgrown the stock fork and shock, the RFLOXA Hawk31 Max fork and RAB53RV 265L shock kit upgrades both ends at once, with adjustable compression, rebound and preload. The fork and rear shock are also sold on their own. In stock drivetrain parts are handed to the carrier within 1 to 3 business days.
Frequently asked questions
Should I keep the belt or fit the 420 chain kit?
Keep the belt for quiet running with no lubrication; the reinforced belt stretches less than the OEM one. Choose the Primary Chain Kit 420 if you ride in sand and mud or run an upgraded controller, because a chain handles grit and torque better.
Does the Primary Chain Kit 420 change my gearing?
No. Its 13T and 30T sprockets match the factory ratio, so acceleration and top speed stay as they were. Only the stage between the motor and the jackshaft changes, and the final chain to the rear wheel is untouched.
Which rear sprocket sizes do you have?
The FabiRide 7075-T6 rear sprocket comes in 48T, 52T, 54T, 56T, 58T and 60T for the 420 chain. It also fits the Talaria Sting, Talaria 3X and E Ride Pro.
Does the RFLOXA suspension kit fit the Light Bee X?
Yes. The Hawk31 Max fork and the RAB53RV 265L rear shock both list the SurRon LBX, LBS and L1e. The kit includes a CNC triple clamp and the lower headset bearing, while the upper bearing is not included.
Can you fit drivetrain parts for me?
Yes. Our Kaunas workshop services Sur-Ron chains, bearings and suspension. Contact info@fabiride.com before you send the bike or the part so we can agree the work.
