The solid tyres on the Unagi Model One E500 should last up to a year of reasonable use, which equates to around 400-600 miles while riding. This is far from a definitive prediction as these tyres can last in great excess of this, or greatly less. The mileage that you'll receive is really down to the load and way in which you ride your scooter. Riding the scooter at high speeds and at higher loads will wear your tyres out much more quickly than somebody who is riding the scooter at lower and more considerate speeds.
Do these tyres require any maintenance?
Thankfully, due to the nature of solid tyres, very little maintenance is required of them. We would really just recommend any users of the Unagi Model One to regularly check their scooter tyres for any excessive wear and tear. Ideally, tyres should be changed a little more often than every 400-600 miles, however, if you have any queries about the condition of your tyres, please do submit a ticket containing several images of the wear and one of our customer service advisors will be with you shortly.
