Specialized is the world leader in MTB and e-MTB.
There are many reason IGHs are not put on MTBs:
"Belt drives are used to carry uniform load and cannot handle frequent fluctuations of load and can fail easily as compared to chains. Chains can carry heavy load at low speed without slip which makes it an ideal drive to be used in bicycles/motorcycles".
Unquote.
You can easily find an e-MTB for US$13,000-15,000. No premium e-MTB has the belt/IGH.
Seriously, see some EMBN videos and you will understand why.
There are many reason IGHs are not put on MTBs:
- Heavy weight
- Shifting the centre of gravity rearwards and upwards
- Smaller gearing range (hard to beat the 510% range of a 10-51T cassette)
- Far more gears (12) in the derailleur system
- Less efficient power transfer
- Impossible to select another size chainring on a whim
- Lack of control of the IGH gearbox: a mountain biker typically uses all 12 gears and has a precise control of choosing gears
- Slower shifting of the IGH
- Difficult field repair of the rear wheel
- Vulnerability of the belt to the twigs and pebbles; and mud.
