My husband is 300 lbs. What is the payload for this bike? Do you recommend another that would be more suitable?

The maximum recommended weight for the folding ebike Mariner Step-Thru is 300lbs. Your husband should be fine with this electric bike, but some components may wear down a little bit faster due to his weight. He might be better off getting the Yukon, or the Step-Thru Yukon, which have a maximum recommended rider weight of 320lbs. The maximum rider weight is listed for all our models in the 'Compare Bikes' section of our website.
