Of the two I think the Zen has better specs with its proven, well respected Bosch motor and batteries. You can usually get service on Bosch equipped bikes from any LBS that is Bosch certified, especially from Trek bike shops.
I have always been a LBS guy buying from dealers who could provide local service when needed. Up till recently all my bikes have been Bosch. I am retired so I have had the time to learn how to do most of the care and feeding of my own bikes, acquired a decent set of tools and actually have fun doing it.
I recently purchased my first direct to customer bike from Evelo. It has been a very good experience. Evelo designs their own bikes, assembles them in Taiwan and only sells in the USA. They have been around since 2012. They have a 4 year 20,000 mile warranty and a customer satisfactions guarantee where you have 21 days after the bike arrives to send it back, at their expense for a full refund, no restocking fee.
Their tech support is amazing, knowledgeable, helpful and easy to reach, often answering the call when you make it or back to you within an hour or two. If you are unable to do the repair or part replacement yourself, they will arrange for a LBS to do the work and pay for it.
By the way, changing a tire with a belt drive is really no more complicated than doing so with a chain drive. The only real difference is the belt driven bike's rear wheel with its internally geared hub, is a bit heavier.
This is the new model Omega by Evelo that I bought. It is an awesome bike with great power, 750 watt Dapu motor, 720 Watt battery, very well built and a Enviolo Automatic CVT with belt drive
