a bike shop told me it's not sell separately... 

Why is there a honeycomb beside your bike? Hehehe. You went off roading.

Dear sifus,I just bought a china brand 20" folding bike(Speedgear) with 7speed rear and single speed on the crank.Cycled a few rounds yesterday around the park and I find it hard to cycle uphill or slope. Any recommendation upgrades/mod to fix this problem?

Still can't make up my mind to get which 1.
All of them have similar price range. What the different between them?
Pro & Con?
Dahon
Visc P18 - RM2399
Dash P18 - RM2499
Mu P27 - RM2599
NEW Vigor P9 - RM2399

Tern
Link P9 - RM2800

Congrats on your purchase. If you want to stick to single chainring, I suggest you look for a more sturdier bash guard. Something from Lite Pro should be good. You can try looking for 55T or 56T chain ring and just change it. The X7  modding to 10 speed will probably cost RM800 and the X9 RM1000 (approx. figures) but off course it will be much cheaper if you mixed the usage. Mainly there's 4 components that needs to be change. The 10 sp cassette, the chain, the RD and the shifters.

I think for a foldie, although it is good if we can put in top notch drive train components but it's not that critical as mountain bikes or road bikes. When you are in a race, gear shifts have to be precise and crisp but as for recreational foldies, as long as it doesn't break or rattle or jam, it should be fine. If you see expensive Birdy, they shod the 6K bike with only Shimano Alivio.   But it functions perfectly. The problem with P9s Neos RD is the cage is really short and when you hit down to the highest 2 gears, ie. the 2 smallest, the RD springs are so sprung up that when you change gear, it releases the spring and the release of the spring flings the cage and in tandem the chain so strong that it flips out! The Dahon Dash and Visc has longer caged Neos. I wonder why they don't just use that? They only give that when there's multiple chainrings.

I have modded my Dahon Vigor to SRAM X5s and it cost me about RM600 and the rear shifting is good and acceptable although not as smooth as my other 2 Dahons which uses the classic old Shimano LX. Maybe it's OK if you don't ride much hilly areas but myself, I do a lot of Genting Perez and Sempah. Also I used to ride Fraser's Hill so gears are important to me. As long as it changes, it's fine. Even the Shimano Acera is better than the Neos.

is the tern link P9 already discontinued? i google to check for specs, but to no avail. even on the official website. can someone confirm this?
