Can you ride a bike faster at night or morning?

Answer 1

If it's a bicycle you're talking about, it won't care much either way.

But the rider, who's also providing the power, can be affected.

Someone who has a hard time waking up in the morning may ride faster in the evening. Someone used to getting to bed early might do better in a morning race. Evening/nights often offer cooler temperatures.

If you're in a hot climate, night riding might let you go faster.

If you're in a cold climate, day riding might let you go faster.

If you need good visibility, you're probably faster during morning/day than during evening/nights.

If you're talking about a motorcycle, then engines have a little more power in cold air. OTOH tires will grip better when they're warmer.

Then again, in some place you get problems with the asphalt bleeding out when it's hot, causing slick spots that can cause riders to slide and lose control.

If you're clocking a real-life ride through a city, traffic will play a huge role. Congested traffic can slow you down a lot, even if a bike has a certainability to weave through obstacles.
