“Absolutely delighted with my LIOS Exactor. As a complete amateur only starting to take my biking a little more seriously, Steve was really helpful and approachable. The bike fitting was brilliant with a superb level of precision and care.”

“Brilliant experience with Steve at LIOS, both with the speccing of my bike and the fitting session. Well worth considering if you want something special in a crowded market.

The bike is superb, build quality is outstanding.”

“WOW my new LIOS Exactor exceeds expectations.  Steve’s attention to detail through the Retul bike fit and building the bike is fantastic to experience. The custom features and finish are amazing, with my LIOS talked about as the best looking bike in our club. I bought the Exactor to be quick and it really is; knocking chunks off my PBs on the first rides even though I am heavier and older than when they were last set! I really hope LIOS continues to be so successful for Steve and the LIOS rouleurs.”

“My previous Cannondale CAAD 12 is a good bike, but not a patch on the LIOS Bullet; my first proper ride felt like getting into a Porsche GT after driving a people carrier. The SRAM system is excellent, the frame is responsive and absorbs far more road bumps, the wheels seem to glide with little rolling resistance and the hydraulic disk brakes stop you very quickly. Overall, an excellent bike and I only wish I'd bought one sooner.”

“Excellent. Very professional set-up. Impressive selection of bikes to suit all needs. Very thorough on taking measurements to get the right fit. Quick build. Very good value for money. Very personal service to the customer.”
