Using a fan while riding indoors, if my main goal is weight loss?

No. Weight lost by sweat is water weight. Your body needs water, and you should replenish lost water as you ride and/or immediately after. People have reduced their weight through sweating to meet an ...

Does a bike exist that is both very light and does not need to be ridden in a hunched over position?

Consider trying a recumbent. They fail on your "light" requirement, with weights well above a diamond-frame. However for a crook back, sitting in a comfy armchair is magical compared to being on a ...

Is it worth buying a lighter bike? If so what kind?

IMHO, it's not the weight that is hurting you the most. While weight makes a difference and a lighter bike would be much better, it's too common in cycling world for people to use weight as a proxy ...

Could you reduce the weight of a Santa Cruz Chameleon down from 12.82 kg to 10kg (2018 model)?

Breaking the rules with a kind-of non-answer and personal opinion, but... 1) Mountain bikes should be heavier than a cyclocross bike. It's got a suspension fork and frame and wheels need to be ...

Normally I say bike weight limits are conservative and more about liability and Lawyers than engineering and would have a large safety margin on published weight limits. However, this frame design ...

Do fat cyclists bonk?

Bonking occurs when your body cannot metabolise stored fat (and muscle protein) fast enough to replace the glycogen reserves, you deplete the reserves in your muscles and liver, and eventually you run ...

Max weight of child, for rear bike seats - why is it always (seemingly) 22kg?

While Criggie's answer explains the reasoning behind the limit, the reason why the official limit is almost always exactly 22kg is simple: that's the standard. The 22kg limit comes from the European ...

Using a fan while riding indoors, if my main goal is weight loss?

My answer is essentially the same as Adam's, but phrased a bit differently. The less adequate your cooling, the lower the power you'll be able to sustain. Power directly correlates with calories burnt....

Bicycle weight limit (carrying capacity) increase

On a non-folding bike, I'd look at the wheels, and probably replace them with 36 spoke touring wheels and reasonably wide, tough tyres (e.g. 35mm). The tyres absorb some of the shock loads. However a ...

Which part(s) has the greatest slope of price per pound(kg)?

Using a fan while riding indoors, if my main goal is weight loss?

No, it does not mean that. Losing water is not weight loss, unless it's the night before a fight (judo, boxing) and you need to get your weight into your weight class, then happily gain it back. Your ...

Are the benefits of light, high end equipment (such as carbon fiber frame) defeated by wearing a backpack?

Per your comment you are currently riding a very cheap bike. Upgrading to a more decent bike will bring a lot of benefits, not just lower weight. Weight is most important when going uphill or when ...

Max weight of child, for rear bike seats - why is it always (seemingly) 22kg?

To summarise the comments 22 kilos is about 50 pounds, which is slightly above the "recommended maximum one-person lift" weight of 15-20 kilos. The "average" child who weighs 22 kilos is big enough ...

How would one determine if enlarging the loadbearing screw holes for the bike rack is a good idea?
