I grabbed some of the envisioned accessories and spent some time trying them on for size. First up, it's got to be able to carry a big cooler to have fun on the beach. CHECK! Of course it will go on an upper deck/motor mount frame that isn't there but it's obvious it's going to fit and what the deck length needs to be. The whole point was to carry an articulated trailer that could carry people. I decided to base the seating on some simple white plastic chairs from Ikea. In this mock up you can see the reverse seat that will mount to the trailer or deck and the front facing one that be on the articulated trailer. Both need to go up about 8-10" from the height you see them at. And if you imagine another axle with fat tires under the chair in the background you're starting to see it. Even if you're carrying a passenger you still want to be able to carry a little cooler on the beach right? No problem, when the upper deck is on it will sit a bit further forward and flat. Of course you can put more stuff on top and bungie too! Like a battery powered mixer for Magurita's! The battery capacity is going to be at least 20Ah at 36V... and an inveter would fit so you can plug in anything you want. Humm... With the articulated trailer attached you can fit two large coolers between the seats, or a wheel chair. You know theres is no reason the trailer can't have a surfboard rack and maybe a canopy... There are some sketches to be made, but the priority is completion of the primary bike drive and decks. This is a fun project and I can't wait to have it 4 blocks from this beach.. I am so spoiled and lucky!
