Can I Use The Bike Size Calculator For Women’s Hybrid bikes?

Yes, typically women’s specific bikes have different hybrid bike frame sizes to unisex bikes, but they are sized in the same way. Women tend to have shorter upper bodies than men, so the frames are shaped differently.

Women's bikes tend to have shorter top tubes compared to a similarly sized unisex bike. This makes the bike slightly shorter than a unisex bike so a female cyclist will feel less stretched out on a women’s bike.

As this doesn’t affect the seat tube length (saddle height) or stand-over clearance, our bike size calculator is suitable for both unisex and women’s specific bikes and the information in this bike size guide is relevant to women’s hybrid bike sizes.
