Every manufacturer makes correct and easy to read bike sizing graphs for each model . This makes up for not being able to try it out for yourself before you customized it.
The manufacturers also state geometry such as the head tube angle. With all of this information. It is quite easy to pick the correct type for you.

This is the most popular mountain bike frame material. Alloy is relatively cheap, corrosion-resistant, and pretty lightweight (especially the widely spread 6061, 6063, or 7005 alloy). Most often a bike will be 6061 aluminum.
MTB e bike types:
There are 3 categories of mountain bikes on the market,the mountain bike types are listed below:

Each of those will also divide into different mountain bike types. Each type will perform best under the specific discipline it is designed for. Different types of bikes will have differently styled frames, suspension, components, and more.
Mainly we customized below 6 types MTB e bike :
Before you customized the MTB frame , you'd better choose your wheel size.
Wheel size plays a huge role in the performance of mountain bikes. The reason behind this is pure physics – higher diameter wheels roll faster over obstacles, where wheels with a smaller diameter react faster. Here is where you get to decide what you care about!
26” was the wheel size standard for decades. When mountain bikes first rolled out, almost all of them featured 26” wheels.
27.5” wheels are the in-between size and the sweet spot for many riders. They were designed to roll better than 26” wheels but also feel more agile than 29” wheels.29” wheels are found on most XC bikes today, and are slowly making their way into other disciplines (even DH!).
29” wheels weigh more than the smaller sizes, but thanks to bigger diameter, obstacles are easier to handle.
