I don’t often leave reviews but credit where it’s due, I’ve bought trials bikes from most of the trials shops now. Bought one from John lees. Purchased on a dinner break over the phone and the bike was packed, shipped and arrived to me within 24 hours. Small issue with the bike but Chas went way out of his way to help and got it sorted. This shop has restored my faith in buying a used bike. Chas was so upfront , helpful and fast! Thanks for the bike chas hope to deal with you when I’m due another one! 👍

Purchased my first 2T here, a Beta 200. It was strange, I’d tell friends where I was buying it and they all told me, “oh Chas will look after you.” And look after me he did! DVLA caused some delays and Chas took care of it all and helped me throughout. My next bike will also be bought from Chas! I’d have no hesitation in recommending John Lee & Sons.

Particularly for the service from Chas. Greatly appreciate the top customer service he has given me on a bike that was supplied by John Lees which I won from a competition site. Really unexpected as I didn't purchase it as a customer
