Answer:
FALSE
Step-by-step explanation:
If you go downhill being on a high gear, you could lose control of the bike, because of the fact going downhill makes you go a lot faster than going uphill, if you go in high speed downhill it could also lead to your chain breaking of your bike. So it would be a false statement. ( also the wind speed going downhill would be higher which, yet again, you can lose control...)
