The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Can-Am Spyder RS has a 737 mm seat; the Harley-Davidson Street Glide Trike sits at 721 mm — a 16 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 74 cm for the Can-Am Spyder RS and 72 cm for the Harley-Davidson Street Glide Trike.
That makes the Harley-Davidson Street Glide Trike the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Can-Am Spyder RS gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
