Looks good and a nice ride

Absolutely fantastic bike!

What a great bike this is, I just love it! My days out are so much more fun and easier than days on my previous bike. The gears and brakes are smooth, the bike is light and it's a pleasure to ride. To be recommended!

Great Bike, great service

Not the bike I was originally going for but with help and recommendations from lads at Formby cycles went for a Marlin 6. Couldn’t be more pleased. Great to ride May thanks
