An ebike is a fantastic way to commute with less effort. Alternately, its capabilities can be utilized as added assistance to reach a destination faster! Ebikes afford a versatility that accommodates flexibility of choice for the cyclist. A virtual tailwind awaits you every ride!

A fact about an ebike I feel needs to be elucidated and emphasized:
Average "per-minute" physical effort is a rider's choice and pedaling an ebike can equal or exceed the physical effort for riding ANY bike. The difference pedaling an ebike is that one can travel faster and reach a destination in less time.

Ohm's law formula: volts x amps = Watts. 36 x 6.9 = 248.4 watts. That rounds off to a 250 watt hour battery. For a bike with a 250 watt electric motor, it is a small capacity battery compared to many e-bikes on the market.

Let me just say this about "stealthy" ebikes: the biggest problem I have encountered is that drivers don't realize how fast ebikes can go. So I wonder if not having the battery visible will really confuse them.

I, personally, have a big ol' external battery, because I have nothing to prove and nothing to hide.

Although it was fun blowing past everyone on the first hill, I don't have anything to prove either. We all had a good laugh. My choice was something that would give me some help on the hills, so I wouldn't get dropped, but at the same time, not blow the group away either. The lightness of the bike is nice. On the flats, I don't have any trouble keeping up and I'm not using the battery.

36V x 6.9Ah = 248.4 Wh
For a bit of contrast, my 65-pound Juiced CCX bike has a 13-pound Li-on battery which equates to a 998.4 Wh capacity. The CCX is a steady commuter steed. Sort of a Clydesdale but it handles like a much lighter bike.

I bought a new ebike yesterday. My first ride was today.

I rode 55 miles. The battery was down to about 10% when I finished. ...I had to conserve the battery on the way back in, because I really needed it.

A nice looking "stealthy" ebike! What are the battery voltage and watt hours?

Haven't seen anything on watt hours. This is what is listed for the battery though. 36V/6.9A

..VERY COOL BIKE, BUT NOT ENOUGH BATTERY POWER AND BATTERY LONGEVITY,

After a few more rides, I am starting to get this figured out a little more. I rode a metric today, and by conserving the battery along the way, I had 8% battery left when I finished. The course had almost 5,000' of climbing, so it wasn't flat. The 250 watt motor is plenty for the hills and keeping up with the group, which is what I bought it for to begin with. It would be nice to have a little more battery life, but I can always buy the add-on battery if needed. The drawback I see is the weight. Being around 26 pounds, I find it tough to keep up in a fast paceline (25 mph+). The motor shuts down at 20 mph. But even at that it rides pretty much like a normal bike. There are some components that can be changed out to get the weight down some, and I may explore that.

Conserving battery energy translates into significant cycling effort. Rider input on the ebike enables a faster overall speed which helps a cyclist to keep-up on climbs as well as conserves battery energy.

With rider effort and e-motor assistance, a cyclist accomplishes a faster speed enabling a cyclist to complete a ride in less time.

Keeping up with the group on an ebike can equal and even exceed a rider's typical non-ebike per-minute effort, especially on the flats.

When we are in situations where we are going over 20 mph, I turn the motor off. It doesn't help any to have it on. Every mile I can go without the battery gives me that many more overall miles. On the hills, less effort. On the flats, more effort.

David, I started this blog thread for the benefit of cyclists with a curiosity/interest in ebiking. All perspectives are welcome...
