“Thanks ever so much amazing job on the bike. Wow what a difference it made. I must have been going about 1mph faster than before with less effort.” Martin C (club road cyclist)

Is wet here, but Jacob has taken 0.5 secs off his time. 45.15, if it was dry he would get another half second off, so looking good” Jacob (BMX racer)
Tom is a genius and saved my cycling career. Ian P (endurance cyclist)

Tom is incredibly knowledgeable and exceptionally helpful. Thank you. John (competitive cycle racer)

Tom understood what I wanted, and also what I didn’t know I wanted. Excellent rebuild. Bike now feels better than when new.  Nick H (club road cyclist)

My bike was definitely feeling it’s age the other day, so got in touch. We had a small chat to see what the possibilities of upgrades were, as well as to find out what I needed from my bike. I left it with Tom and I can safely say he has worked his magic. I was kept up to date with how the work was going as well as asked which improvements I wanted to make. My bike is an absolute joy to ride and I will be back for further improvements! Thank you! David M (Touring cyclist)

A fantastic same day service on my road bike. I was really impressed with the booking system, speed, communication and personal bike advice. Love the sustainability ethos of bringing used frames back to life in the form of a custom built bike built with top quality parts. I would fully recommend Ewhurst Bikes and thank Tom for the excellent service. Alice (Touring cyclist)

Tom at Ewhurst Bikes is a total legend. He collected my bike, transformed into something much better and now I am able to get out on it. Having lots of fun riding through the woods around where I live. If it wasn’t for him, my bike would still be under a dust sheet in the garage, all broken and unloved. I highly recommend his services. He’s a nice bloke too.  Sarah (casual cyclist)

Frame repair – Titanium Carbon and Aluminum

“Finally finished my Marin rebuild” “just wanted to say how spot on your welding was.” David R

The detailed design of titanium bike frames, analysing the cause of the failure and getting the strategy right on how to repair titanium frames is critical.

Yet the accepted designs, grade of titanium used and norm on excessively pretty welds without understanding the critical design details, leaves most titanium frame manufacturers providing flawed frames.

We have repaired many of these frames and analysed the failures and strengthen and resolve these design flaws.

The detailed design is critical to achieving a strong a beautiful frame.

Yet designs try and fix the issues without realising they are creating increased stress concentrations that lead to faster catastrophic fatigue failures and propagating thereafter from the sharp micro cracks.

Here is a nice Van Nicolas frame with a relatively mino but critical flaw in the pretty weld, that caused the failure

That flaw would gone unnoticed , because it looked pretty

These frames are well worth saving and strengthening properly

We know about what matters because as professional engineers, eg we’ve worked heading up aircraft engine design teams, where the use and design of carbon, aluminum, titanium components are critical to make sure you don’t fall out of the sky on the way to your holiday destination ✈️
