nowdays, all price are going high!
low stock supply, but demand are very high. i do remember last time trinx ka2016 or 2016d is priced around rm600-800 but now used bike is rm800. even java TT is around rm600 and now is rm1.1k

following the market trend right now as for ur daring question, i cant suggest anything within ur price. but i could recomended few brand that i know

Price level < 500 RM
try to find oscar vogue, so far the clamp are better than most brand within this budget

Price level 500 - 1000 RM
crossmax also good, only the package groupset are so so. while raleight calypso (bodwalk look alike) last time is around RM800, but now i heard is rm1.1k. brand like trinx,xds, java if u can find within these range i could be nice
if i were u and dont mind used bike,
i'll wait till oct until dec. saw many buying bike as a trend ad monotorium from the banks leaves some people got a lot of money. i dont think cycling lifestyle will be forever for trending follower.

lets hope we can get cheap quality bike for a jackpot price!
