@cam I dunno, I think it depends on the price range. There are some light e-bikes but they tend to be higher end bikes.
For example:
* the Vado SL weighs ~15 kg and is apparently on sale right now for $3k, see screenshot. (There鈥檚 also an EQ version with fenders and a rack for $250 more but that鈥檇 be heavier)
* The Specialized S-Works Turbo Creo SL is 12.28kg in size L and is apparently on sale for $4,500 (see screenshot)
It also depends on exactly how much weight the bus rack can handle. If there鈥檚 a specific agency that you usually use, they might make that information available. It might be worth checking.
