Primary Belt-to-Chain Drive Install (e-moto)

Full primary belt-to-chain conversion for Surron Light Bee, 79Bike Falcon and similar e-motos using the Warp9 Warp Drive or Heavy Hitter kit. This is a rear-end teardown, not a bolt-on — the swingarm comes off the bike to get the jackshaft out.

Teardown

• Battery disconnected, bike on the lift
• Rear wheel removed
• Rear brake caliper and cable guide removed and secured
• Suspension linkage unbolted from the swingarm
• Swingarm pivot bolt removed, swingarm pulled from the frame
• Belt cover, motor pulley nut and keyway removed
• Jackshaft removed, belt and both pulleys off

Conversion

• Jackshaft sprocket installed with alignment spacer as needed, threadlocker, torqued to spec
• Motor sprocket installed and keyed
• Chain fitted and master link set
• Chain line checked for straightness before anything is torqued down

Reassembly and adjustments

• Jackshaft, swingarm and pivot bolt reinstalled and torqued
• Suspension linkage reconnected and torqued
• Rear wheel installed, axle torqued, secondary chain tension and rear wheel alignment reset
• Rear brake caliper reinstalled, pads centered on the rotor, lever feel checked
• Motor position set on the tensioner cam for correct primary chain slack, adjuster bolts locked
• Motor nut torqued, belt cover reinstalled, battery reconnected
• Full bolt-torque check, chain lubed, test ride, final tension check

Includes one free primary chain re-tension after break-in (about 50 miles) — new chains stretch, and this keeps your bearings and sprockets healthy. Kit billed separately.

Fitment: Light Bee and 79Bike Falcon. Ultra Bee and E-Ride Pro require a different kit — confirm with us before booking.
