Very good to know about Kenda.

I'm trying Continental Tour Plus on the back, with the replacement Marathon Plus I received on the front at low pressure / low stress. It should outsee the bike!

I had a Big Apple 2.15 on the front at minimum pressure for the 'pneumatic suspension' effect to reduce overall rolling resistance and improve comfort. It did.
Sadly they can't be fitted on the rear as its cross section is too 'fat'
Something Decathlon need to look at: a redesign of the rear to move the wheel back so you can fit 2"+ tires to take 100Kg
