With hills in your life I'm pretty sure the early Rad City will prove gutless while the new version will likely be MUCH "sportier". There's a huge difference in the early direct drive hub equipped bikes vs. the newest geared hub version. Much available regarding that difference so I won't repeat it all here. I WILL say, the more you weigh and the bigger the hills, the more difference will be apparent between them. The new 'City also comes with hydraulic brakes. Yes the mechanicals will stop the bike just fine, but after driving both there is little imagination required to know which you'll prefer.
The
Ride1up (R1U) is a worthy competitor when compared to the RAD City when considering the 700 model. The difference will be in the HUGE popularity of the RAD bikes, which WILL transfer directly to resale value and how easy the bike will be to sell should you decide to move on to nicer/more expensive bike, or the need to bail on the e-bike plan completely comes up. I'm pretty sure you'll notice the fact many people will be commenting on the support available for the RAD product as well.
I do ALL of my own work on my bikes, mostly because I want it done right, but also because I enjoy doing it. It's part of the hobby for me. Because of this, I am NOT a fan of bikes sold using proprietary parts that must be returned to a dealer for service. The TEK line up are perfect examples of such a bike. The RAD and the RIU are both examples of bikes built using non proprietary parts that can be sourced from most places selling bike parts. That's a big deal if doing your own work, and long term maintenance costs are an issue. -Al
