it can be taken out... but i doubt it is any easier than the conventional hook type...

i mean the conventional ones that is boot mounted by straps and hooks...hitch mounted ones only work on specific cars if i am not wrong.. not all cars...

It can be removed from the receiver.

This might be useful to you.

how tight is tight...

budget bikes sometimes backfires on your tight budget if the stuff on the bike fails within a short period... so, you might need to think twice...

you can go as low as buying more reputable branded bikes that is non disc equipped, 8-speed MTB bikes from giant or some lesser brands but it will still cost you a whopping 1xxx...and you risk spending loads of money upgrading it sometime down the road when you get serious....

you need to go walk around a few shops to gain some insights of how low you can get and then decide if you want to start now or save up a bit more and start later with a better base....

there is an MTB thread you can check with if you want more opinions

it can range from as cheap as RM200++ all the way to RM1xxx depending on the brands.... roof mounted ones of course costs a whole lot more but it also is more flexible in case you want to change options of putting up canoes and stuff....

the hitch receiver is part of the chassis or welded to it.. it's not installed or removed by choice...

the black portion at least....

why not consider SeaSucker?

.
Probably like this type?

why don't you just give up on the hitch type since your car might not have it?


it's never gonna look nice.. it's more for function than to look good...be realistic about it...
