V9 Aluminum
V 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 V1, V7, V7i |
| Frame Size | Rider Height | Effective TT | Standover Height |
| Small/Medium - 46cm | 5'2" - 5'8" | 55.8cm | 29.5" |
| Medium/Large - 54.5cm | 5'9" - 6'3" | 58.9cm | 32" |
| PUBLIC V9 Aluminum |
| Frame Size | Rider Height | Effective TT | Standover Height |
| Small - 46cm | 5'3" - 5'6" | 55cm | 29.5" |
| Medium - 50cm | 5'7" - 5'10" | 57.5cm | 30.8" |

*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.
Shipping and Assembly
The PUBLIC V9-AL (Aluminum) is our lightest diamond-frame bike to date. Its sleek, lightweight aluminum frame stands apart with premium tubing and sporty geometry that strikes the ideal balance between performance and comfort.
The Shimano 9-speed drivetrain delivers a wide gear range, making it easy to transition from navigating city streets to climbing hills with confidence. A Rapidfire trigger shifter ensures smooth, responsive gear changes, while commuter-tested riser bars provide precise handling. The V9-AL is finished with our Premium Sport Saddle and vegan leather bolt-on grips for immediate comfort.
Weighing in at just 25 lbs, the PUBLIC V9-AL is approximately 20% lighter than our average steel bike. Rack and fender mounts come standard, so you can outfit it for commuting, errands, or weekend adventures.
