I used to blow dry with the leaf blower but I'm much more satisfied with this unit,

The hose is all rubber so if you contact the bike you don't have to worry about scratches, the air uses heat from the motor so it warm air, and you can direct the air a lot better than the leaf blower. Only thing about it, you better put ear plugs in or you'll be deaf by the time the bike is dry.
I use the same dryer, works real well. It is branded on at least 4-5 different purposes. Same item is sold at dog - pet events for drying the pooches.
Mine is unlabeled and was about $150 when I got it.
The warm air effect is really good for your dogs.
You definitely need hearing protection using the narrow nozzle, especially around edges where the air will scream.
When using it on the dogs I don't use the nozzle and the noise level about half (still loud though).
Both the cord and hose are pretty good lengths.
