Reduce tire pressure
For anyone who lives in a place where wintry weather includes snow and ice, it’s a good idea to reduce tire pressure. Patches of ice, snow and even wet roads can and will reduce traction. A sudden loss in traction on an e-bike can result in a fall, so maintaining traction is important, even if it means a loss in rolling efficiency.
Cutting tire pressure by 10 to 20 percent can make a noticeable difference in traction. The bigger the tire, the lower the pressure to begin. Commuters, road e-bikes and gravel e-bikes with tires narrower than 2 in. (50mm) should be running pressure in the range of 50-60 psi. Most of these tires can be run at 40 psi and riders will see a remarkable improvement in traction. Fat-tire e-bikes run much lower pressure due to the incredible volume of air, but even a drop from 10 psi to 8 psi can make a difference.
With an e-bike, a change in tire pressure is unlikely to make for a noticeable change in overall speed. Range will drop a bit and riders may notice a slight drop in acceleration, but the gain in traction will be significant.
Wash the e-bike
Riding an e-bike on roads that are salted to melt snow means a bit more maintenance for an e-bike. That salt will rust steel parts and can cause corrosion on aluminum ones. Depending on how many days a week the e-bike is being ridden, an e-bike will need to be washed periodically. Daily commuters riding roads that see lots of road salt would do well to wash their e-bike at least once a week.
Spraying the bike with a gentle cleaner (Simple Green is a favorite in our garage), hosing the bike off—no pressure sprayers—and then wiping it down is all that’s required. Be especially careful not to direct any spray at the motor or other electronic components. We send old T-shirts to the garage to extend their lives just a bit longer as bike rags.
Lube the chain
Between wet conditions and road salt, an e-bike’s chain receives more abuse in the winter than at other times of the year. After washing an e-bike, wipe the chain down and then use a lube in a squeeze bottle. This time of year, we opt for lubes intended for wet conditions.
The quickest, easiest way to apply lube is to turn the pedals backward while holding the bottle against the chain. Give the pedals enough turns to make sure the whole of the chain has been covered. If possible, let the chain sit overnight and then wipe the excess off. Failing that, wait a few minutes before wiping the chain down.
