But sadly
I want to remain anonymous here. Hehe

Tpu tubes are those thin light weight tubes ?
Nope. Never tried this before.

Also I'm now on tubeless.

Using this
Good

Check the bearings in the rear hub.

Look like it's badly worn out.

That plastic thing will be the first thing I will rip off from my bike after unboxing . Lol.

Next will be the reflectors on the spokes and any other reflectors on the bike.

Check the hub bearings.


Looking at the cassette and the type of axle. I guess this bike must be at least 25 years old

I would advise to go to physical shop and check out the bike there , especially when it comes to size and fitment.

If he is not going to off-road with this bike, get him a hybrid - mountain bike with slick/road tyres.

Using a off-road knobbly tyres on tarmac is not easy, a lot of rolling resistance. Get him a road tyres. Such as maxxis detanator. Good stuff. I'm using this on one of my old mountain bike.




What's your budget ?

Now a good entry level mtb (at least a polygon or camp) starts at around rm3k to rm4k.

For your son to cycle 2km to school , just get a simple hybrid will do.
But most importantly is to get a bicycle frame size which fits him correctly.

True
On road foldie will be easier. Less rolling resistance
