Consider changing the middle chainring to a 34 or 36 and try that before replacing the freewheel. A 14-34 freewheel would require a long cage mountain bike rear derailleur.
Clean and grease the hubs, headset, bottom bracket, and pedals including new bearings where needed.
Remove any unnecessary weight on the bike.
Ride
