Hi,

What is the make, model and size of the bike? You can use the link below to get an idea of the dimensions of the bike you may need.

Bike Fit Calculator | Find Your Bike Size | Competitive Cyclist

I ride Big Box bikes. The latest was $35 used and with a little work it fits and rides great. I have tried clips and clipless but I stick with platform pedals.

If you find, after using the fitCalculator, that the bike you have won't work start checking out yard sales. Mountain bikes have a lower sloping top bar and you can mount city tires for an easier ride.
