Is there any options for me to make it perfectly fit for my height... I am 4'11 and I believe the bike is 49cm I am not 100% sure but with standover I would have to tip toe.
It rides fine.... do you think switching from 700c rimes to 650c rims would make a difference?
The overall radius difference between a 700c and 650c wheel is about 2 cm. Since the height of the frame off the ground is determined by the radius of the wheel, not the diameter, you'd only gain 2 cm. That would give you more stand over for sure but it may not be possible or at least a simple thing to do because it will change the position of the braking surface of the wheel relative to the frame. I don't know how adjustable the brake set up is and if it would accommodate a 2 cm change in rim position.
Keep in mind that your bottom bracket will be dropped so you won't have as much clearance under the bike, that's not likely an issue unless you're jumping curbs or riding off road. But that also means that your pedal will be closer to the ground and that could be a factor in cornering.
In short, I doubt it would be advisable.
