If you have a full motorbike license, you are permitted to ride the Maeving RM1S on the motorway in the UK. With a top speed of 70mph, you can comfortably keep up with other vehicles on the road. However, it is important for riders to use their judgment and exercise caution when riding on motorways.
On the other hand, if you only have a CBT certificate, it is not allowed to ride the Maeving RM1S on the motorway. Additionally, it is worth noting that riding at the top speed for an extended period of time can result in a reduction in the vehicle's range.
