And a cycle is usually a two-wheeler, powered primarily by muscles.
He had some sympathy for moped users and recommended they "claim their space".
"We would encourage the moped users to keep as far left as practical, without encroaching on the cycle lane," he said.
"Approaching a roundabout, they should be checking behind that there is not a vehicle about to overtake them if they are travelling slower than the other traffic.
"Then, after indicating their intentions, move out from the left and take a position in the lane so that another vehicle cannot try and squeeze past them," he said.
"Negotiate the roundabout, indicating their intentions to other road users, and then exit again taking up a position as far left as practical without encroaching in the cycle lane if it continues."
Wairarapa police area commander Brent Register said it was definitely correct that mopeds should not be in cycle lanes. "Mopeds are still motorised vehicles, rather than a cycle."
But he also pointed out it was not good that a moped rider was being crowded out by cars. "Vehicles should be giving room."
His recommendation to moped riders, particularly at roundabouts, was "have a look, and take a bit of road that you need".
