No, it's not. Hunter-gatherers would not have access to most technology. The only way to produce technology you want would be manufacturing, so unless you can build a moving factory the hunter-gatherer lifestyle is doomed. And unless you plan to kill anyone who discovers agriculture and destroy those abomination called cities that some tribes form then civilization will reform again. Think about it in order to make a bike you need metals(mining, which doesn't work in most areas so people will need to settle down. People will also need to heat the metals and shape them into a bike frame, and wheels will need to made from rubber. Each person that works as a manufacturer can't find food, which will need to be brought to them. The best way to produce surplus food is agriculture. Civilization formed so people can use technology to make their life easier.
