Good on ya!
I started cycling with my children (7&8) about 2 yrs ago, mainly during the warm / dry weather, At 23 stones it is a sight to behold LOL, but you know what..... I don't give a fluck!
At first I was really self conscious, actually had idiots double taking and pointing at the fat woman on the bike, I rode past teenagers who snickered and grown men who made stupid comments.... I became the master of the quick comeback to shut them down!!
I love my "Mary poppins bike" complete with the basket, best 150 quid I spent! Me and my kids love it and even took part in last yrs london skyride.... and yep I'm still 23 stones, cant walk far without my back aching, but I can cycle for miles without so much as a twitch.
And with my surgery date looming....., the best is yet to come.
Enjoy your bike, the freedom and the exercise and pay no mind to the fools who stare.... thats my moto .
Peace
