Kevin Really positive 1st impressions after a few rides, something a bit different for a choice of MTB. Well finished and decent spec for the price. Very straightforward assembly. As ever, great service and delivery from Merlin.
Mr Appleby 1st Class service, needed bike quickly & the Merlin team pulled out all the stops & got my bike to me in 3 days, fantastic bicycle at a keen price, highly recommended product & service, will be back soon for another bike 👍
