My son is set on getting a belt drive for the bike he

So, why?


Dad gave him too much money :-)

Now, a shaft drive, that would be great.


Imagine it would be much heavier and complicated, they have been tried and
used on MTB but don’t seem to have been cracked, I think generally the
extra weight/cost though a E-MTB would mitigate that?

Given a choice I’d love a belt drive bike for the commute as I clock up
fairly respectable distances per day which does chew though the drive
chain.

Have to say a belt ticks far more boxes that a shaft. If I were doing
it all over again, a belt would be the answer, you don't even have to
enclose it.
