Best for: Outdoor, rough, or inconsistent terrain like gravel, grass, dirt, etc. - when paired with a mountain bike style tire (knobby, wide).

Or, active lifestyle where a larger profile tire benefits you, like when using a E-Assist device on your wheelchair, or if you simply prefer a larger profile tire to absorb rough terrain - when paired with a large profile road bike style tire (minimal or no tread).

More info:

The Spinergy 507mm wheel is specifically designed for use with a mountain bike style tire (Kenda Booster Pro), or large volume road style tire. We’re tapping into the bicycle market to be able to offer this size - 507mm is typical wheel size for kids bikes and BMX bikes. We use our thick 4mm spokes and our SLX Sport hub to enhance the durability of the wheel for peace of mind in rough terrain.
