Slightly prefer the NN Ninja over my Endless Ultra as it manoeuvres around easier due to the shorter wheelbase..

NN UFS Ninja 90 — the most nimble four-wheel frame in the UFS NN family. Four 90 mm wheels on a compact 273 mm base, agile while holding speed and stability.
A frame this size would normally feel like rolling on rails, but the pre-rockered "V.m" profile keeps it turning easily. Nicknamed "ninja" — an all-round frame that's hard to get wrong. CNC-machined from aerospace 6061 aluminium and, for UFS-mount boots.

Singapore-only express delivery via J&T Express or SPX. Fast, tracked, and free above S$60.
Miss the cutoff or order on a weekend/public holiday? Your order goes out on the next working day and arrives the day after that.
What we commit to is dispatch, not delivery. If your order meets the cutoff above, we pack it and hand it to the courier on time. That part is ours and we hold ourselves to it.
The delivery leg belongs to J&T Express or SPX. Once a parcel is scanned in at their collection point it is in their network, and their collection and delivery schedules are not something we control. Missed collections, driver or route changes and courier system outages do happen, and when they do a next-day parcel can arrive a day or more later than this page suggests.
What we do about it. Every order gets a tracking link the moment it is scanned in, so you can see exactly where it sits. If a collection is missed or tracking stops moving, email admin@inlinex.com.sg and we will chase the courier directly rather than leaving you to do it.
Next-day delivery is a service level we aim at and hit on the large majority of orders. It is not a guarantee, and we would rather say so here than have you find out from a late parcel.
