New bike - Solorock Spin 5

BLUF: Some photos are here.

I wanted something lighter to replace my almost 32lb 1990s Dahon Mariner and I read about the Solorock Spin 5 on here. This is a 20" folder that weighs a claimed ~23.5lbs with pedals, fenders and seat. It has a 9 speed 11-32 cassette, a Shimano Tiagra (4600 though) and a 52T chainring. It has to magnets to keep the bike folded and if you position the fold right, you can roll it folded. This bike in what the manufacturer calls a 80% matte black color.

Solorock is a Canadian importer of random electronics from China like dishwashers and window AC units. They seem to have rebranded this bicycle and imported it for sale in the US and Canada since a bike with a very similar frame is sold in Asia and the EU (FSIR Spin 5.0).

It replaces my Dahon Mariner in my multi-modal commute (DC Metro). Although the fold is not as compact as my Dahon, the fact that this bike is almost 10lbs lighter and the fact that it can roll folded, it is already my favorite.

Dislikes:
  • Not as well engineered as some mainstream folders like Dahon. I can fold my Dahon Mariner in less than 15 seconds while this one takes close to 30s. Perhaps this can be attributed to my relative inexperience with the Spin 5's folding mechanism but I don't feel confident that the folding time can be significantly improved upon.
  • Raising and lowering the seat post causes scratches on the post

The scratches are likely caused by the grooved mechanism that keeps the seatpost/saddle pointed straight. You can remove this mechanism (removing a tiny Allen bolt), and there will be more clearance for the seatpost. This will also allow you to install any grooved or non-grooved 33.9mm seatpost.

Mine, an FSIR Spin 5.0, is down to 9.5kg (20.9lbs) sans any weight-weenie parts.

I just weighed mine and it was 24.2lbs (everything stock, including seat, pedals, rack and fenders). At some point in the future, I might use your parts list from the other post to try get the weight down a bit more.

Thanks for the tip! I'll definitely give that a try. I've been eyeing the red Litepro seatpost for a while.

..you need to get two standard Dahon or Tern size seat tube sleeves to remove the seat post groove lock since it is one part with the original sleeves. I recommend GUB or Litepro plastic sleeves, use them on my Spin's and they solve the scratching problem excellent.

...wait, is there written "limit weight 80KG" on the seat post? In this case, the post is 330g only and there is no need to get a carbon one. I had two and they both failed under my weight, one was 269g (TAT) and one 312g (LitePro)

Gotcha, I'll get some Litepro sleeves from Aliexpress. The seatpost does say 80KG and is fairly light but I'm using the scratches as an excuse to get myself some alloy Litepro ones for some color
