Today was another freakishly fantastic weather anomaly so I had to get out for a road trip.

I wanted something that could challenge the new build so I loaded the bike in the car and headed for the Blue Ridge Parkway, specifically, the climb up 215 from Rosman and then south to Richlands Balsam, the highest point on the Parkway road. Strava recorded the ride at 50 miles with 5710 feet of climbing but I forgot to start the damned app until about 3 miles up the road. It was probably more like 53 miles and 5900 feet. Starting elevation 2200 feet and turnaround was 6053 feet.

All up weight including me, bike and a couple of water bottles and snacks was 203 pounds. 34 tooth Race Face chainring and a 11-28 cassette. New BBS-02 and a 48V Dolphin pack with Panasonic NCRB cells rated at 13.5 amp hours.

All I have for monitoring the battery is the C963 watt indicator and battery gauge. I finished with 2 bars showing but on the final 5 miles I was driving it pretty hard at PAS 5 and the batter gauge was bouncing between 1 bar and 2. Mostly 1 under load. I put a volt meter on the battery when I got home and it was reading 45.8 volts.

For most of the ride, I was riding like I didn't have the motor, putting out my usual puny 30-50 watts. My goal was to ride as normal, but keep my heart rate under 160 at all times. On most of the climbs the C963 was showing between 100 and 180 watts. I adjusted PAS and gear selection to keep the wattage in that range while also keeping my peddling effort steady.

I had a few anxious moments early in the ride, though. I had just gotten to the first long 10%+ grade and was cranking away and all of a sudden I got a big whiff of Magic Smoke (burning resistors)!! Naturally I freaked out, stopped and felt the BBS02 and smelled it. Nothing. Barely even warm. This is 4000 feet up in the middle of nowhere with the cleanest freshest air you can image. The smell dissipated. I get back on and ride away. Ten minutes later, same smell!! Stopped again, motor still barely warm to the touch and no smell. No frigging idea what was going on!!

Turns out the smell was from cars passing me going the other way. I must have been subconsciously expecting problems so my brain delivered.

Anyway, it was a beautiful day for a bike ride and having passed this test, I am REALLY liking the BBS02. I got it to make long rides more enjoyable as I get older and if it can do this, I think it can handle anything I am likely to throw at it in the future.

I forgot to mention that the battery pack was charged to 90% using Luna Cycle's new intelligent charger. (Very nice charger!!)
 
To be clear....
Was this a 50 mile round trip, up and down....or 50 miles bottom to top ?
Any idea of the time taken actually cycling ?
Either way , it's an impressive performance if you were only pedalling at such a low effort.
 
This is a pretty typical experience - which is good. The unit doesn't contribute much power until its required. You can force it to do so by changing into a 'harder' gear (assuming you are using PAS) so long as it is below the programmed max speed, but no reason to if you are happy with the speed you are travelling at! Enjoy! :D

P.s. can you update your profile for those that are not in US? It helps to see a city or state in your avatar to know whether its worth looking up to go to myself 8)

The Blue Ridge Parkway is a National Parkway and All-American Road in the United States, noted for its scenic beauty. The parkway, which is America's longest linear park,[3] runs for 469 miles (755 km) through 29 Virginia and North Carolina counties, mostly along the Blue Ridge, a major mountain chain that is part of the Appalachian Mountains.

Nice country over there, from what I've seen on Aerial America Smithsonian Channel.


To the guy below, press the X button next to the "edit" button that you did press....... and its deleted!
 
The total trip was 50 some miles. And with 5710' of elevation gain, there also came 5710 feet of descending (good brakes are a must in the mountains). Total time in the saddle was just under 5 hours. Other than the descents, I was using PAS boost most of the time, usually around 100watts according to the C963 display.

Anyone have a recommendation for a better way to track power on a BBS02? I don't want to spend the big bucks on a Cycle Analyst and I honestly think that if this ride is typical of what I can expect from the battery pack, I probably won't suffer from range anxiety for 99% of my rides and won't wind up using a fancy power meter very much. Has anyone used one of these:http://www.amazon.com/gp/product/B0...e=as2&tag=xbnijgbr-20&linkId=YSWLOU3DNSBIEQHW
 
I suppose if you buy it from Amazon it will be just fine. I bought the same watt meter on eBay and it went bang and let all the smoke out of the wires. In the end it was easier to get a replacement from Luna..... And it came with the correct connectors for my battery (Luna, of course).

An accurate wattmeter is essential for power management.
 
Woodland is spot on, the luna comes with connectors I believe. I bought mine on Amazon because I use Andersons and wanted to add my own connectors. I also have a CA3 and Grin Shunt. I move it from bike to bike when I think I want more information. But these wattmeters are very helpful for A LOT less money. Two CA3 setups and I'm in $300!
