A two-wheel type is more stable on level ground, while the almost universal one-wheel type has better maneuverability in small spaces, on planks, in water, or when tilted ground would throw the load off balance. The use of one wheel also permits greater control of the deposition of the load upon emptying. It’s offered with a choice of puncture-proof or pneumatic wheels; we recommend the puncture-proof option, for total peace of mind. If you’re working with a small garden or vegetable patch then something smaller and lighter might be more convenient, but this is a fantastic all-rounder.As the name suggests, the ancient Chinese wheelbarrow (wooden ox) was made of wood. In his text dated 430 AD, Pei Songzhi states that the ancient Chinese wheelbarrow had a central wheel and an axle on which the wooden frame was constructed. The wheelbarrow’s design was a representation of an ox. How was the wheelbarrow made in ancient china? In the 1970s, British inventor James Dyson introduced the Ballbarrow, an injection molded plastic wheelbarrow with a spherical ball on the front end instead of a wheel. Compared to a conventional design, the larger surface area of the ball made the wheelbarrow easier to use in soft soil, and more laterally stable with heavy loads on uneven ground.

Key specs – Capacity: 85l/150kg; Wheels: One; Material: Steel; Puncture-proof wheel: Yes; Assembled: No Since dikyklos ( δίκυκλος) and tetrakyklos ( τετράκυκλος) mean nothing but "two-wheeler" and "four-wheeler," and since the monokyklos ( μονόκυκλος) body is sandwiched in the Eleusis inventory between a four-wheeler body and its four wheels, to take it as anything but a one-wheeler strains credulity far beyond breaking point. It can only be a wheelbarrow, necessarily guided and balanced by a man...what does now emerge as certainty is that the wheelbarrow did not, as is universally claimed, make its European debut in the Middle Ages. It was there some sixteen centuries before. It may be tempting to go for the biggest wheelbarrow you can afford, but the largest barrows tend to be heavy and cumbersome to wheel around, and they’re not cheap either. For most people, the standard 85L capacity is plenty, even if you have a large garden. If your garden is a bit more compact, or if you’re just looking to clear out your vegetable patch, a smaller size should be fine.Honda Worldwide | News Release | April 27, 1998".

[6] It was written that in 231 AD, Zhuge Liang developed the vehicle of the wooden ox and used it as a transport for military supplies in a campaign against Cao Wei.
