Finally got the Gazelle early in the week and have put about 30 miles on it. The upgraded Nyon (MY21) is exactly what I had wanted as far as a computer, so very glad I did that upgrade. Apparently it is not an easy retrofit, took the shop 6 hours, but since I negotiated the installation in as part of the purchase I avoided some costly labor fees there.
Really enjoying the ride. The IGH and belt are nice, and I love the shifter and being able to make smaller adjustments, as well adjusting at a stand still. Very glad I got the mid-step to be honest, I was worried about how it would look, but it's very convenient and don't feel like I"m getting a physical at the doctors office when I stand over the bike.. The 1.75" wide tires have stood up to basic trails / gravel just fine. The Bosch motor / battery are great, though battery life leaves a bit to be desired. I finished my ~20 mile ride this morning at 48% left. See below for breakdown of time spent in each mode. I'm confident I could get a "lazy" 30 out of it no problem, so with a spare battery, 60 miles is easily reachable, and probably 80 is I was thrifty with eco mode.
I know there were comments about the Specialized Mastermind being a great system for data, but just wanted to give Bosch some props here.. see below for the screenshot from their web portal which takes the data from the bike computer via BT phone sync (or WIFI, if you turn it on in range and sync that way). Of interesting note is the export options, including .CSV. All of the graph options (speed, altitude, cadence, motor power contribution) provide data, you can just only pick 2 at a time on their website.
Still have my heart set on the Vado SL 5.0 EQ, but it will be a while.. I hit some rain and heavy wind on the way back home today and wasn't even slightly worried because I knew I had the big motor / battery to help me out. I would've been worried on the SL.. but I imagine as my fitness level improves, so will the viability of the SL.
Next up, an additional light for some night forest road riding and testing out those SPD shoes (Pearl Izumi) and pedals he was raving about..
