TECH ER30 Rear Shock — E-Moto

A high-performance rear shock engineered specifically for lightweight e-motos, delivering a balance of support and sensitivity at the rear of the bike.

The ER30 comes in two lengths, and they are not interchangeable - pick the one that matches your bike:

• 283 x 80mm - E-Ride Pro 2.0 / 3.0 / SR (direct mount), Sur-Ron Light Bee X (linkage mount), Ventus One / One Plus (linkage mount), 79Bike Falcon Pro / GT (linkage mount)
• 288 x 85mm - all Talaria Sting models (linkage mount), Altis Sigma / Sigma MX (direct mount)

Along with pre-load and rebound adjustment, the ER30 uses CTS (Compression Tuning System), a patented Formula and TECH Suspension design that allows fast, tool-free tuning of low- to mid-speed compression damping.

Spring rate options:

• 78.8 N/mm (standard) - suitable for average-weight riders
• 105.6 N/mm (optional) - recommended for heavier riders or aggressive terrain

Performance features:

• Piggyback reservoir: increased oil volume improves thermal stability during long or aggressive riding.
• Internal Floating Piston (IFP) with dual seals: prevents oil and gas mixing for consistent damping and long-term reliability.
• High-profile MDU bumper: derived from TECH trials suspension - improved bottom-out resistance and progressive end-stroke feel.
• DU bushings: smooth, low-friction articulation with excellent durability for high-load off-road use.
