D8i Alfine Disc
D Model Size Guide
Find Your Size
A bike that fits properly is more fun to ride. The guides below offer size suggestion based on height in inches. If you have measuring tape, you may also determine your size by measuring your leg length plus one inch, which is your stand over measurement. For all bikes, we recommend at least 1 inch of space between you and the top tube of the bike. When in doubt, contact our customer service team via email at customerservice@publicbikes.com.
| PUBLIC D8i Disc |
| Frame Size | Rider Height | Effective TT | Standover Height |
| Small - 50cm | 5'3" - 5'8" | 55cm | 30.5" |
| Medium - 54.5cm | 5'9" - 6'1" | 58cm | 32" |
| Large - 59.5cm | 6'1" - 6'6" | 61cm | 33.5" |
*Please note: some riders may be a little outside of these height range recommendations but prefer the feel of a larger or smaller bike. Stand over height measurement is not as important as how the bike geometry feels while it is being ridden.
