Sun EZ-3 and EZ Tri Classic Recumbent Trike

Sun EZ 3 SX and CX Delta Trike
Sun EZ-3 / Tri Classic

The EZ Tri Classic is very comfortable with a large cushy seat. It is a good trike for someone who needs exercise and local transportation but doesn’t think they have the strength or coordination to ride a two-wheeled traditional bike or recumbent. It is slow and heavy but stable at lower speeds.

Sun EZ Tri Classic Recumbent Tricycle

The EZ Tri Classic seat is high enough to make getting on and off easy. We have had customers with medical conditions such as Parkinson’s and severe arthritis that thought they wouldn’t be able to ride who found the EZ Tri Classic a joy. One rider’s condition forces him to walk with a walker but he was able to enjoy the EZ Tri Classic on his first ride.

Its low-speed handling is very easy to get used to. It is easy to get onto and off of, even for some riders who have trouble walking. One of the nice things about a trike is low-speed stability. You can climb as slowly as you like and not fall over, and you can stop for a rest without getting off. We can give it custom low gears to make it climb any paved hill.

It is heavy at 67 lb and not the bike for someone who wants to go fast, even on descents. After taking a sixteen-mile ride on one I have to report it is even comfier and not as slow as I had expected. Over 20 mph it’s high-speed handling is poor-to-unsafe. Its high-speed emergency handling is terrible. The front rim brake and rear disk brake work well, you shouldn’t have any trouble keeping your speed down. The rear brake pulls the bike slightly to the right.
