Compass will sell the 7-speed folding Powabyke via its 100 000-customer mail-order catalogue in Holland, Germany, France, Austria and Switzerland.
Sales into IBDs in those countries is also being sought by Powabyke. Spain and Italy are also on the hitlist.
Powabyke claims to have sold 10 000 bikes in the UK in the 18 months since the Bath company was founded. The average selling price of a Powabyke is £600.
Compass Watersports has 14 000 product lines and Powabyke MD Nick Child said Compass "has the perfect consumer audience for potential users of Powabykes."
"Consumers interested in the great outdoors are the right people for Powabykes. Many of our existing users attach their bikes to the back of a boat or caravan and take them on holiday as an easy solution to pottering about."
There are five powered e-bikes in the Powabyke portfolio, including a tricycle and a shopper bike as well as 21-speed MTB.
