No the S5 is 14 inch wheel.

I bought from a local dealer in Sydney, who import them directly from the manufacturer and provides local warranty / service. I know buying from Aliexpress etc can sometimes be cheaper, but I'd rather pay a bit more to have local support.

Just took some comparison pics hopefully that shows what you are looking for.

I paid AUD$1500 for the S5, and I got it from a local dealer that gets his wheels directly shipped from the manufacturer to Sydney.

The S5 uses the standard 2.125 inch wheel and the i5 uses the 1.5 inch wheel, I'm not currently at home so I can't take a picture of the tyres. I'll try to take some pictures when I get home. Given the form factor of the design it is relatively easy to carry, but at 15kg I'd still prefer if the S5 has a handle of some sort....

Hi All, Fisrt time poster, I’ve been reading this forum since I started riding EUC in April 18. My first wheel was the i5 and I’ve bought a s5 518wh version and received it towards the end of June. I’ve also purchased and received my Z10 a few days ago. Back to the topic, I’ve done over 700km on the s5 now and it is still rides very smooth with a top speed of 40km/h (warning beep starts at 35km/h and tilt back starts at 40km/h) and I’m getting realistic range of 35-40km on my rides. Personally I feel both the i5 and s5 are fantastic and reliable wheels and I think what happened to Randalab’s wheel looked more like mishandling from the merchant rather than from the manufacturer. Both of my IPS wheels came in perfect condition. I’m not backing IPS in anyway I’m just sharing my thoughts and experience with the 2 wheels I have from IPS. P.S. The attached screen shots are a bit old and only shows 649km on the i5, took those screenshots as personal milestone of achieving 1000km combined mileage on EUC in 5 months of riding.
