Do
Go hard. Push yourself every now and again.
Smile. Riding a bike is awesome, look like your enjoying yourself.
Wave/say hello to fellow riders. It’s a nice thing to do.
Ask if people are OK when they’re stopped by the side of the road/trail. Most of the time they will be, every now and again your assistance may prove a big help.
Learn to fix your bike. It will save a couple of quid but will also and will also mean you will have a better appreciation of how things work
Observe the rules. Whilst also taking them with a healthy pinch of salt.
Encourage others to ride. But don’t push them too far or they will never ride again.
Don’t
Take it too seriously. You’re a grown up on a push bike, you look like a fool, embrace that.
Drop litter. Stuff it in your pocket and take it home.
Faff or me late. Bit of a personal one this as I don’t have a huge amount of spare time, if we’re meeting at 10am, be ready ride for 10am, don’t then need to get changed, pump up tyres, generally mess around.
Forget to blow a kiss the the driver who just cut you up/questioned your parentage/was a dick.
That’ll do for a start.
