I had bought the iBert the last summer and tried it out without the baby first. Then I rode with the baby for a few blocks to test the balance before I went on a longer ride.
When I ride I know I am not strong enough to go uphill and I don’t try and push myself. I have also mapped out routes that, although they take longer, have less traffic and official bike lanes. I tested the route on my own before I rode with my baby.
