It weighs 57 pounds and stands 38.4 inches tall, making it easier to place in smaller spaces. This bike targets shorter riders and seniors, offering magnetic resistance and pulse sensor tracking.

It supports a high weight capacity, which exceeds the Sunny bike’s standard limits, making it suitable for heavier users.
