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.
Saddle width should match sit-bone width plus 20-30 mm depending on riding posture and flexibility. Sit-bone width can be measured using a pressure mat or estimated as 65-70 mm for most adults. Road saddles tend narrower (120-155 mm); MTB and commuter saddles wider (150-180+ mm). Available widths within a product line typically span 142-154 mm or 155-168 mm.
