    ZOOM · Shock-Absorbing Seatpost

    Float Over Every Bump

    Most e-bikes have front suspension and nothing behind you — every pothole, curb and cobblestone goes straight up your spine. The ZOOM E-Bike Shock-Absorbing Seatpost puts 45mm of tuned suspension right under your saddle, and the included universal shim kit means it drops into virtually any e-bike. Bolt it in, sit down, and the road goes quiet.

    45mm of Travel

    Rough Roads, Smooth Ride

    E-bikes are fast and heavy — you feel every crack at 25+ MPH. The ZOOM's suspension head soaks up 45mm of impact before it ever reaches you: potholes, expansion joints, brick streets, hard-pack trails.

    Riders switching from a rigid post call it the single biggest comfort upgrade you can make — bigger than a new saddle, bigger than lower tire pressure.

    Parallel-Linkage Design

    Precision Shock, Not a Pogo Stick

    Cheap suspension posts bounce straight up and down and change your leg extension with every hit. The ZOOM uses a parallel-linkage head — the same architecture as $250 premium posts — so the saddle moves back and down through the bump, keeping your pedaling position constant.

    The result: high sensitivity to small chatter, rapid absorption of big hits, and no bob when you pedal hard.

    Tuned to You

    Swappable Springs for Your Weight

    One spring can't fit every rider. The ZOOM ships with a coil spring matched to its size and supports swappable spring weights (75kg and 100kg classes), so lighter riders get full small-bump sensitivity and heavier riders get real support instead of bottoming out.

    The multi-angle saddle clamp fits standard rails and adjusts to your exact riding position.

    Universal Fit — Shim Kit Included

    One Post. Any E-Bike.

    Seat tubes come in half a dozen diameters, and ordering the wrong one is the #1 reason suspension posts get returned. We solved it: every ZOOM seatpost from BackToModern ships with a precision-machined shim kit that adapts the post to the common seat-tube sizes (27.2–31.6mm range and beyond).

    Measure nothing, guess nothing — it fits your bike out of the box.
