Yeah , I thought mine had different components.
I originally just bought it for the wheels but then things spiralled and I ended up doing a full rebuild . It’s just the right size for me so it was worth it in the end, I struggled to find the right material for the saddle and ended up using an old guitar case, it’s a bit ripply but more comfy than substitute one I had on there .
Best bit was the completion and taking it for the first test run . Rides nice and smooth .
