I purchased my second Ebike from Halfords (the first one got stolen) it has been my means of transport to and from work, and has been an enjoyable experience. How ever - low end E-bikes will have faults. So i took my Ebike to a fantastic gentleman for a full chain and cassette replacement from Norms bikes in smithfield market behind castle court - brilliant store and lovely guy and rplaced my stock cassette and chain with a much better and reasonably priced one. But.. My breaks and pads were being eaten through - as they are 'what you pay for' so as Norms Bikes has a very long waiting time, i decided on taking my Ebike to McConvey Cycles. From the moment i stepped foot into the store i was greeted with a warm welcome from staff, who made chain reaction and halfords look like rookies - with their knowledge. I had my breaks re alignmened, replaced and working beautifully! For a reasonable price and my bike (though i had booked it for one day) was available for a collection just a few hours later. My advice to anyone buying a low end bike - prepare to pay slightly more replacing parts in the future but definitely use these guys. I also have a speech impediment and staff were fully patient and understanding with me. Great store and staff.
