I had a similar issue but this was after an accident. My findings with this bike is you basically get what you pay for.
I changed the saddle and tyres, and was advised by my local shop the gears and brakes were of the lowest level quality wise.
I have had the bike 3 years and it cuts out sometimes. The brakes also need constant adjustment.
