Because it's reasonably light, strong, inexpensive, easy to machine and join together. All characteristics that makes it a good choice to build bike frames off.
It has bugs
- aluminium is cheap- aluminium has a low density- aluminium is not easy corrodable- aluminium has convenable thermal and electrical coductivities
Aluminium alloys are stronger than pure aluminium, which is comparatively soft. Pure aluminium is also considered chemically reactive (thus the layer of aluminium oxide which coats the metal due to oxidation). Pure aluminium hardly exists due to its strong affinity with oxygen in air. In fact, aluminium foils and beverage cans are also alloys of aluminium, with about 92 to 99% of aluminium. So likewise, bike frames are also made of alhminium alloys because of its characteristics of being strong and lightweight.
A 29-inch bike is suitable for riders who are typically 5'4" to 6'4" tall.
Because it isn't very dense and is very strong!
A suitable substitute for bike pedal grease is lithium-based grease or marine grease.
Most bike hubs are aluminium. Aluminium comes from Bauxite ore, which is refined and the metal aluminium extracted. Axles and bearings are generally steel, which comes from iron ore.
The suitable height for a 58cm bike frame is typically for riders who are around 5'10" to 6'1" tall.
A 16-inch bike is typically suitable for children around 4 to 6 years old.
Aluminium bike frames are generally lighter and less expensive than other materials, but they can be less comfortable due to their stiffness and can be prone to corrosion. Additionally, aluminium frames may not provide as smooth of a ride as frames made from materials like carbon fiber or titanium.
Yes, bike pannier bags are typically waterproof and suitable for all weather conditions.
Yes, bike shoe covers are typically waterproof and suitable for rainy weather conditions.
