Each bike comes with either one or two helmets, per your request. We also include a complimentary rain poncho because yes, sometimes you do get rained on when riding somewhere. It happens. When it does, you can either choose to put on your rain poncho and soldier onward, or just find a dry pit stop and wait it out. The rains in Northern Thailand rarely last longer than 20-30 minutes, so hitting a coffee shop is a good way to ride out the weather if you prefer to not drive in the rain.
