Hello, I'm looking for a MTB to join my kids on a rides, been looking at some of the bikes but since I'm absolutely clueless about all the specs all I know is That I would prefer a bike that is on a lighter side and its decent enough! I'm 5.5ft tall. Budged up to around £600. My 11yr old son has a Squish MTB 26 and is so lovely to ride it, looking for something similar but obviously more robust (hence the weight from too much sofa time during lockdown!) Are there any decent bikes in Halfords? Or im better at searching the local bikes shops? Any pointers will be greatly appreciated!
