Perfect overview trip of the city w great guide and a lot fun!

Our guide Becky was very knowledgeable, energetic and fun. You see many great city sites in the 3.5 hour trip. I was a little nervous about riding in traffic but there are bike lanes and Becky helped us throughout with tips for riding and crossing, and when to stop and look at things. There were 8 of us and I liked the small group. These are not e-bikes and are easy to ride on the mostly flat streets. That said you need to be careful not only of cars but other riders and pedestrians too. We occasionally had to walk them in busy areas which was the safe choice. It's totally worth it and very doable. (We are in our late 60s and pretty fit). You will end up with a good sense of how the city is laid out, some history and what you want to do in your remaining days on London. I highly recommend this trip.
