By eliminating all the cadence < 60 records most of the low Pr records are gone too. For 100/100 slope is 5.5, cutting 20% to get mechanical power would make it 4.4. Seems unlikely though it would be "4.4 times you."

Boost ratio and Pm as a function of Pr

Coming soon.

A little more context. Here's the individual chart for 40/100 with all records where Cadence and Pm and Pr are >0 And here's the chart with records where cadence > 59. These charts were done in LibreCalc. It did the best fit linear trend lines. For the combined chart above I estimated the...

It's with some concern that I post this chart as it refutes my whole understanding of how the xx/xx and xx/100 tunes work. I rode up and down the same street in approximately 1 mile laps in 20/20, 20/100, 40/40, 40/100, 70/70, 70/100 and 100/100. The chart shows Pm as a function of Pr for...

Bosses on the top of the top tube also.

Yes, the ranger extender battery is an option. The display will show charge levels of both batteries and you can program which battery gets used first. I did a short range calculation as part of my Pm vs Pr experiments. 20/20 tune with an avg 10 mph showed 110 miles on 90% of a full battery...

Sidebar about the Spec website: All the SL 2 4.0 and 5.0 models are back plus they added unequipped versions of the 4.0.

Just finished a ride with 20 segments, about 1/2 mile long in 1-10 xx/xx and xx/100 tune settings. Now I get an error saying can't download file. Please try again later. Also, turns out there is a 00/00 microtune setting as well as a 00/100. Setting the display to show rider power and motor...

More conflicting info This is the ride data graph from the Spec app showing segment where I was in 10/100 then changed to 0/100. From this it apears that the motor was indeed off. This directly conflicts with the Spec chart showing rider power needed to get max motor power. WTF?

Correction to my comment above about the motor making noise when turned off and how easy the bike is to pedal unpowered: I set micro tune to 0/100 and assumed that meant the motor was giving 0 support. I was just looking back for info about Spec published motor power and saw in post #21 that...

I was using 10/100. No motor cutting out because I could never pedal hard enough to get the motor up to its max power. 10/100 gives a modest boost all the time. 10/10 would be very different as motor power would plateau at 1/10 max power although I suspect Ease setting xx doesn’t actually cap...

Mother Nature smiled on us today so I could get in a nice first real ride. Did 7 miles back and forth on a straight flattish stretch in my neighborhood trying out the different dynamic micro tune (xx/100) settings then an 11 mile greenway ride I've done many times in the past. The back and...

Just now Spec website shows SL (not 2) 5.0 EQ in silver available from warehouse in XL and in stock at a few stores in M and L. $5249.00! $150 more than the new SL 2 5.0 EQ. Also curious, my LBS has another SL 2 4.0 size M in stock. Certainly other stores throughout the US have SL 2 4.0 and...

Regarding saddles: I swapped the Spec OEM seat for a Serfas RX I've been using on my Trek FX3. The Serfas is the same length but 1" wider and noticeably softer. Haven't ridden the new bike with it yet but I know it's been comfortable on my acoustic Trek. I don't ride the Trek for as long as...

Hi rochrunner, I see you are in Rochester Hills MI. My wife and I are OU grads and I lived basically at the intersection of 26 mile road and Canada for 50 years. Small world. I followed your posts about loving your SL 5.0 but wanting the lower step over height. I'm in the same boat regarding...

Weird, when I ordered my bike on Jan 20, Spec showed 10+ in stock and the bike arrived the LBS said it would be at their store in 5-7 days and it was.

It's a Turbo Vado SL 2 5.0 step through. Color is called something like deep lake blue matte. It looks blue-green in the picture but just looks blue in real life. Picture was taken about 90 minutes before sunset on a crystal clear day so that probably adds some yellow to the color. Weirdly I...

New Bike Day finally arrived. It only took about ten days from order with LBS to delivery but the weather here in Nashville has been too bad want to bring it home. Today was the first sunny warmish day, 55 degrees but 20-30 mph wind. Just rode it a few miles around the neighborhood. First...
