I'd imagine it would be fine but you may want to measure up and check your airlines oversized baggage policy. Most of them have a limit of about 3m in total dimensions (height + length + depth).
I've booked a bike, which is classified as 'sports equipment' with easyjet, there is no stated size limit and a total weight of ~32kg I think. They're used to surfboards so assume I'm fine re the dimensions...
