Product Reviews

“Great communication and fast delivery. Whole purchase experience was very smooth and product is great. Cruzee bike is great quality and was super easy to set up and get moving.”

Chelsea

“Love the Cruzee! Super light and durable. Easy to put together and adjust. Lowest seat position fits our short 2 year old. Fast delivery.”

Josh

“This is the second Cruzee we’ve bought from Cycle Nation. It’s such a great wee bike. Gave the first one to our daughter for her second birthday. Two weeks later she was racing around a pump track. It’s so easy for her to ride. She was cornering and coasting really quickly. We’ve just got one for our 18 month old. Once again Cycle Nation has the best price and service. Arrived very fast. I would definitely recommend the Cruzee as a first bike. It’s very intuitive for kids to ride. And it is so light, which is helpful when they are young and may need to jump into the buggy or be carried.”
