Loose spokes after only a few rides I have recently joined the cycling world after committing to losing weight. I am a heavy rider at about 28st (390 lbs) and have after some advice gone for a GT Avalanche. I have had the bike less than a month and only have around 15 miles on the bike. 

I use the bike to travel to work which varies from light off road to road. 

I was riding back from work and realised that the wheel had started to buckle. Upon getting home I have noticed that some of the spokes were loose. Is this normal and if not is it due to the weight the bike is being asked to carry? Will a home fix be enough to mend the issue?

Update:

I have contacted the seller who has advised me to get booked for their free 6 week service where they can service the bike and they can also true the wheels.

The question I have now is until I am able to get the bike serviced am I able as a temporary measure able to fix this at home and use it as I use the bike for getting to and from work?
Unfortunately, most bikes are only rated to 300lbs or less. However, if this is a new bike, you should take it back to the shop and get them to fix it.  They can't claim they didn't know you were a heavy rider when they sold you the bike.

You might need to get more substantial wheels with more spokes. Wheels designed for touring bikes might be more appropriate. Also, when riding, you need to be careful to avoid potholes and other bumps in the road and don't go up and down kerbs. If you can't avoid a bump, lift your weight off the saddle so your legs and arms are acting as suspension&nbsp;&ndash; this applies to riders of any weight and it's more comfortable for you as well as the bike!
