It has become a staple on most children's Christmas wish lists - and now Halfords is doing their bit to help out.
Thanks to our latest competition, in association with Halfords and 2Chill, two lucky children will win one of Halfords' best-selling children's mountain bikes worth up to £450.
And just to make Christmas that bit easier, whether you win one or buy one, the Halfords team will put them together for you for free if the bike costs £250 or more (or for just £10 if it costs less than that) - so all you have to do is wrap it.
Halfords' Voodoo range of mountain bikes offers lightweight aluminium frames and best-in-class engineering for the entire family - with options in a range of men's, women's and children's sized frames.

Two lucky winners can take their pick from the Sobo, Nzumbi or Nantai children's Voodoo models.
- For six to nine-year-olds, The Sobo (£350) is an ideal option with 20" wheels.
- For eight to 11-year-olds, The Nantai (£450) has 24" wheels and would make a great fit.
- For nine to 12-year-olds, The Nzumbi (£450) is perfect thanks to its 26" wheels.

As well as their Bike Building service, Halfords also offers a free bike health check to ensure whichever model you choose it will remain in great condition long after you've started putting it through its paces.
