Started doing some workout with my Roadster!
I use CycleDroid app on my phone with GPS 'ON'.
It is really a good app!
Please trust me, don't get a Roadster if you love to ride it fast or if you want a lightweight bicycle.
It weighs a ton and what I enjoy in it is, it is suited for max. 10 km/h, that speed range is where maximum fun an enjoyment is, very stable, stops in 3 secs with both brakes applied (:-P), handles awesome, and you will feel like it is gliding, I mean very smooth.
If you try to ride fast on a roadster, you will get tired soon, very soon indeed.
Some idiot(s) peeled of the stickers in my Roadster and thrown away on road :-(
Will need to print some close to original logos.
