FAQ
Mid-Drive vs Hub-Drive
- Mid-drive – Mainly used on mid/high-end bicycles. The transitional torque is known to be smoother, also the weight reduction is more balance on the bikes’ geometry.
- Hub-drive – Cheaper to make. Compared to riding a standard bicycle, it might take some time to get used to the location of the mass.
Foldable eBike wheels & tires
In the past, most foldable bicycles had skinny tires on small diameter wheels that served the purpose to save as much space as possible. Today, you’ll see many folding electric bikes with chunky fat bike tires, which are the opposite. Fat bike tires allow you to ride on multiple terrains with ease while riding an eBike with skinny tires you’ll only feel safe on only well-paved areas.
- Fat bike tires – Multi-surface riding, better comfort. Generally 20″ diameter wheels, 3″ to 4″ wide.
- Skinny tires – Faster and smoother on paved roads, better mileage due to less friction
PUNCTURE RESISTANT TIRES
A folding eBikes is not your typical bicycle. The market for folding electric bicycles is rather limited, and most people expect a hustle-free ride – that’s why most folding e-bikes are equipped with puncture-resistant tires. Most bikes in this review are using a rear-hub motor, which makes removing a bike tire rather complicated.
Spoke vs cast wheels
Almost all bicycles these days come with wheels that use spokes instead of a solid alloy. The main purpose of spokes being used on bicycle wheels is to absorb vibration, evenly. Alloy wheels on the other hand are better on paved roads only. ‘Cast’ wheels are mainly made of alloy.
