Seatpost Shim for Electric Bike

Adjustable Seatpost Shim for Electric Bikes

Overview

A compact, easy-to-install seatpost shim that lets you fit a standard seatpost into a larger e-bike frame or fine-tune saddle height without replacing parts. Built for stability and corrosion resistance, it keeps your ride secure and saves you time and money compared with buying a new seatpost or frame adapter.

Benefits

Get back on the bike faster — swap or adjust a seatpost in minutes without extra tools.
Keep your preferred saddle and post when upgrading or changing bikes, avoiding costly replacements.
Improve ride comfort by enabling precise seat height adjustments to match your posture.
Reduce rattles and side-to-side play for a steadier, safer ride on variable terrain.
Durable finish resists salt and moisture, lowering long-term maintenance needs.

Features

Simple slip-in design that converts one seatpost diameter to another (shim style conversion).
Anodized aluminum body with a stainless steel clamp bolt for secure fastening.
Multiple size options to cover common conversions used on electric bikes.
Thin-walled profile to minimize added stack height while maintaining strength.
Works with standard saddle clamps and most quick-release or bolt-on seatpost collars.
