This is the same model (orange) I bought. It collapsed to one side after I jacked it up and try to move it.
The vendor says it is suitable for 240kg but from the looks of it the material used are not that strong at all.

So ... some feedback from using local custom made product Master Paddock

1. Lifter arms can be a bit longer
2. Jacking arm, can be much longer. I had to use my feet to push it down.
3. Hooks for the spools, can be made with thicker plate
4. Bike tyre actually touched the dolly after lift
5. Feels very unstable when moving it around. Resorted to having the maintenance stand out.
6. After 5x the dolly bend.

Note:
I have already feedback to Master Paddock. He did offer for me to send it after the first feedback (points 1,2,3,4,5) but I am against sending it back since it took more than a month to reach me. Just sent him number 6 as well. He went silence on me after the first feedback.

So anyone wants to order from him, please make a point to ask him to extend it or better ride down to his workshop to make the necessary measurements. Different model has different points. Learn this the hard way.

Good points are
1. Acceptable material thickness mostly
2. Design is OK but can really be improved
3. Wheels are good
4. Even provide tool for the assembling the nut and bolts

a bit off topic, how much strength do you need to lift a bike with paddock?
I have one and I can't seem to lift my bike even after watching multiple youtube vids about it.. push down the paddock handle and rear tyre wont even budge 
bike weight about 200 kg

so technically I can add a long metal stick at the handle to increase leverage right? maybe I also need to find welder to do that
