Strida 5.0 vs 5.1?

Hello: New to this forum and Strida in general. I am looking to purchase a Strida. I saw an ad recently for a Strida 5.0. I was wondering what the difference between that and a Strida 5.1 was. Thanks T.I.

The 5.0 had scalloped brake rotors and the 5.1 and later have circular rotors. The 5.1 may also have slightly different frame bends to better accommodate the optional 18" wheels, although I’m not certain of that. The 5.0 has black spokes, and the 5.1 and later, some have black spokes, some have silver.

Thanks for the information.
