Because before the invention of the chain drive, the driven wheel would only turn as fast as the pedals turned. and the only way to get some decent speed was then to make the drive wheel as big as possible
The Opel Mokka SUV has a built in bike rack. It is built into the rear bumper, and is able to hold up to three bikes.
Safe and reliable options for kid attachment for bikes include child bike seats that attach to the rear or front of the bike, bike trailers that can be attached to the back of the bike, and tow-behind bikes that allow kids to pedal along. It is important to ensure that the attachment is securely fastened and meets safety standards before use.
The type of bike that is mostly used form BMX riding are the purpose-built BMX bikes.
Before the "safety bike" there was the high-wheeler AKA Penny Farthing. That design had a tendency to flip over when braking due to the position of the rider(high up, far forward). Once they had the concept of chain drive figured out, it became possible to move the rider back and down, making the bieks far less prone to flip over on braking. They became safer to ride, hence "safety bike".
The best options for using bikes for college transportation include investing in a reliable bike, using bike racks on campus, following safety guidelines, and exploring bike-sharing programs.
The recommended bike tire pressure for optimal performance and safety is typically between 80-100 psi (pounds per square inch) for road bikes and 30-50 psi for mountain bikes. It is important to check the specific recommendations for your bike and tire type to ensure the best performance and safety.
Most bike parts are generic, and built to certain standards. As long as you're able to figure out which standard your bike is you can get parts for them from pretty much any bicycle shop. The bikes are made by/for a company called HM bikes.
if it was built strong yes it can. but most bmx bikes can

Yes, there is typically a weight limit specified by the manufacturer for bikes to ensure safety and optimal performance. Exceeding this limit may result in damage to the bike or potential safety hazards.
It didn't and it hasn't. The safety bike merged/morphed step by step into bicycles as they are today. In fact, if you look at a cruiser or a Townie, they'll be really close to the early safety bikes in performance and design.
For optimal performance and safety, maintain a bike tire pressure of around 80-100 psi (pounds per square inch) for road bikes and 30-50 psi for mountain bikes.
