Spike is a folding trike with seven gears. He is an entry-level (cost wise) model in the world of three-wheeled recumbent cycles. Just the thing for us first-timers.
The trailer is a frame with an unattached collapsible plastic box. A cloth top keeps things tidy inside. I don’t believe any of this is weatherproof but the unit is way less expensive than the weatherproof trailer I had originally picked out. If we end up upgrading our trikes to a more serious model, the trailer upgrade will follow.
