What matters for e-bike riders
E-bikes weigh 20-30 kg compared to 8-12 kg for acoustic bikes, which fundamentally changes how sizing affects handling. The extra weight actually improves stability at speed but makes low-speed maneuvering and stopping more critical — ensure you can confidently put both feet flat on the ground when stopping, especially if you're new to cycling. Step-through frames are strongly recommended for riders with any flexibility limitations, as swinging a leg over a heavy e-bike is significantly harder than a standard bicycle. Mid-drive motors (Bosch, Shimano, Brose) center weight low near the bottom bracket, providing better balance than hub motors which place weight in the wheel. Battery placement (downtube integrated vs rear rack) also affects weight distribution — integrated downtube batteries provide the most natural handling. When sizing, use the same frame size you'd ride on an acoustic bike of the same type — e-road bikes size like road bikes, e-MTBs size like mountain bikes. The motor assist actually makes sizing slightly more forgiving, as you're less reliant on optimal pedaling efficiency.
Fenders & Mudguards sizing guidance
Fenders are sized to two dimensions: wheel diameter (12–20" for kids, 26"/27.5"/29"/700c for adults) and tire width (commonly 23–32 mm for road, 32–45 mm for commuter/gravel, 2.0–2.4" for MTB and kids bikes). Fenders should sit roughly 8–12 mm clear of the tire on each side and overlap the tire by 5–10 mm. Three broad styles: full-wrap fenders bolt to frame and fork eyelets and cover roughly 60% of the wheel for maximum spray protection (best for daily commuters and rain bikes); clip-on / strap-on fenders use rubber straps or P-clips around the seatpost and fork legs and trade coverage for tool-free install (best for road bikes without eyelets); and minimal racing-style ass-savers protect only the rider's backside and are mostly a token gesture for unexpected showers. Kids fenders tend to be plastic, sized 12/14/16/18/20", and clip to the frame with the bike's existing brake-mount or kickstand bolts.
Expert tips
- Size your e-bike the same as you would the acoustic version — a Trek Rail sizes like a Trek Fuel EX
- Step-through frames aren't just for seniors — they're practical for anyone who stops frequently in traffic
- Mid-drive motors (Bosch, Shimano, Specialized) provide the most natural pedal feel and better hill climbing
- Test ride with the battery fully charged AND nearly empty — the bike handles differently with 3-4 kg less weight
