EBG Primary Drive Pulley Kit V2
Primary Drive Pulley Kit for SurRon, Talaria, ERide Pro & Compatible Electric Dirt Bikes
The EBG Primary Drive Pulley Kit V2 is a model-specific primary belt drive upgrade offered here as a grouped wholesale listing. Select the correct bike, motor configuration and belt width; components are not universally interchangeable between models. The kit combines a CNC-machined 7075-T6 aluminum rear pulley hub, a high-hardness heat-treated 420J2 stainless steel rear pulley ring, a CNC-machined stainless steel front pulley, and an EBG carbon fiber reinforced drive belt.
The hybrid pulley construction reduces rotating mass while maintaining high structural rigidity and wear resistance. Precision CNC machining and controlled manufacturing tolerances ensure accurate belt alignment, consistent tooth engagement, and reliable operation under high-load riding conditions.
Package Includes
- 1 × EBG CNC Hybrid Rear Pulley
- 1 × EBG CNC Stainless Steel Front Pulley
- 1 × EBG Carbon Fiber Reinforced Belt (18 mm or 20 mm)

Motor Configuration Guide
| Bike | Motor fitment to confirm |
|---|---|
| Surron Light Bee X / Segway X260 | Compatible keyed-shaft OEM, EBMX, TORP or Sotion motor; VTB Ryuga 52kW requires the splined-shaft configuration. |
| Talaria XXX | Original Talaria XXX motor configuration. Contact EBG for aftermarket motors. |
| E Ride Pro SS1.0, S16/S17, SS2.0, SS3.0 and Pro SR | Compatible OEM motor or the listed VTB Ryuga 52kW configuration. |
| 79Bike Falcon Pro / GT / M | Compatible OEM motor or the listed VTB Ryuga 52kW configuration. |
| Ventus One Plus / Plus Evo | Compatible OEM motor or the listed VTB Ryuga 52kW configuration. |
For ReRode, SRPNT, other motors or uncertain fitment, confirm the exact configuration with EBG before ordering. Send a clear motor output-shaft photo where needed. Use only the options available for this wholesale product.
Belt Selection and Installation
The 18mm option supports general performance use. The 20mm option provides a wider contact surface; verify clearance and alignment before ordering. This pulley kit does not increase motor horsepower by itself.
Included at no additional cost: 1 EBG Belt Tensioning Tool with every V2 pulley order, including wholesale orders. Use it for initial belt-tension setup, verify alignment and clearance, and recheck fasteners and belt tension after the first 50km. Professional installation is recommended if you are unfamiliar with primary-drive alignment.
