If you've outgrown your Gecko's integrated seat/seat post, you can raise the height of your saddle and allow it to slide further from the handlebars to accommodate a larger rider.
A 160mm or 190mm seat post will allow you to raise your seat higher than the max height 17.5" from the ground for the integrated seat/seat post.
Please Note: Item is Seat Post only. When ordering for a Gecko you will need to order a saddle as well. (Integrated seat/seat post CAN NOT be modified to fit on a standard seat post as it does not have seat rails.)
Need to lower the seat on your Hedgehog lower than the stock seat post will allow? A 160mm or 190mm seat post allows the Hedgehog saddle height as low as 18" from the ground. (No saddle needed for the Hedgehog. Your seat already has rails to fit this seat post.)
