    I weighed my hybrid this morning, just for grins, before heading out to the farmers' market. I underestimated: it was 41#, the rear tire felt low, and even with a full compost bin on the way out and full grocery bags on the way back, it still felt quite a bit lighter than the share bike (which looks pretty much the same as the bikes in other cities that I've seen but haven't ridden).

    I have a feeling the extra weight is mostly in the share bikes' wheels. Stands to reason they'd be super bulletproof - not that the wheels on my hybrid aren't, but a friend of DH's did trash one of the wheels on his similar hybrid, jumping curbs we assume, and I expect they want share bikes' wheels to be able to stand up to that and worse. Not least because the front wheel has to be at least more or less true to go back into the docking station!

    Can't remember how many internal gears Columbus' share bikes have, but at least three and maybe five. Not single-speed, anyway.



    FWIW, it seems to me that the heavier the bike, the *less* it's affected by wind. Maybe it just seems more miserable when you're going more slowly overall ... You're obviously less aerodynamic in an upright riding position, but that's riding position and not weight. With more weight, you've got better momentum, and your profile to the wind isn't affected by weight. In crosswinds, you'll be way more stable. And FWIW, it seems to me that wherever you are, you get either hills or wind, not sure there's anywhere where there's neither. Hills are the reason that wind inland *isn't* as brutal as it is in flat coastal regions ...

    I agree the bikeshare bike's weight tends to be in the wheels area, as related to part of the bike station's security system.

    My hybrid that I have been using most daily for last few years where I live, is approx. 29 lbs. and I have 38 mm wide Schwable commuting tires @ 70 psi. My dahon folding bike is around 21 lbs. or less. It has an internal hub, plus front and back racks. (I know weight weenies criticize the internal hub system for this....) Both bikes I have each lifted, onto bus bike rack over the years.

    Honest, with these chinook high winds that often push through, I like riding with my weighted panniers to ..stay upright on bike with the strong crosswinds depending how the route curves and turns.

    It's very true that you're less affected by wind on a heavy cruiser bike than on a light racing bike, but according to my DH who understands the physics of it all, that's because you're traveling much slower (which ultimately is mostly due to the weight of the bike but also your position on it). The slower you go, the less wind is a factor. Maybe that's why riding a cruiser bike here in windy Playa del Carmen works out pretty well for me. On a go-fast bike I'd probably wail about the wind like I always do in the US, but here it's a relatively minor factor.
