If I order a Fat Bike online it will come in a box. Is the assembly hard to do for someone fairly good with their hands?
This depends how much it was assembled before going into the box. I've had one bike that just needed the stem bolts to be loosened and the stem rotated, plus the pedals fitted (using tools provided). The one I bought recently needed a little more work but still only using tools you'd carry on the road plus a pedal spanner. That was a used bike, and had been dismantled just enough to go back in the box.
The seller should be able to tell you exactly what is required. It's well worth asking them.
Important things to be aware of:
- Some bolts need to be done up to a specific torque. On many bikes this can be quite roughly approximated but on carbon fibre and light alloy you shoudl really get a small adjustable torque wrench (sometimes sold as a torque screwdriver). The parts should normally be marked when the torque matters.
- The left pedal has a left-hand thread. Double check that you've got the pedals the right way round, then grease the threads and do them up with your fingers for severalturns before finally tightening with a pedal spanner (a thin 15mm open-ended spanner)
The level of expertise required will vary by the brand and the complexity of the bike. You will need a decent set of Allen wrenches and common hand tools such as wrenches and screwdrivers. I've assembled numerous bike for friends from a variety of sources. The easiest involved installing the front wheel, inserting the seat post, mounting the pedals and handlebars. Another required mounting the rotors to the wheels, the calipers to the frame, both wheels, bars and saddle. Then it also required some shifter and derailleur adjustment. I would suggest reading some of the Park Tool tutorials. Pay particular attention to derailleur and brake adjustments. While it is not rocket science it can be frustrating the first time you do it. If the bike comes out of the box really out adjustment and your attempt to correct it is unsuccessful then bring it to your Local Bike Shop and pay for the adjustments.
