Well put.

to clarify "electric bikes" isn't the correct terminology. The electric bike that the thread is originally talking about, a firefly with a bosch middrive motor is a pedal assisted electric bike. As in, the rider must be pedaling for the motor to be engaged. There are laws that apply to them. They can only go up to 20 or 28mph. After that, the motor doesn't provide any power.

Also, stop calling people fat.

I thought we were calling them ebikes not electric bikes which is an entirely different thing because ebike means pedal-assisted electric bike which is a more accurate description of an ebike than an electric bike.

amen.

this will probably be my next bike:

electric bike or eMoto is actually the correct term for most of what we are seeing though as we're seeing them hauling without any requirement to pedal.

The Firefly might be an eBike but a lot of what is out on the street in the US are really just lighter/slower versions of the Harley Davidson project.

"ebike" obviously is short for "electric bike". The US Federal regulations recognizes several classes of ebikes, which include those which only provide pedal assist, and those which can also be throttle controlled. To avoid confusion, an ebike which only provides pedal assist is often referred to as a "pedelec" (i.e. pedal assist electric bike).

That sounds like a nickname for a pedophile. I like ebike more.

I'm in favor of pedal-assist ebikes limited to 15 mph as in Europe, as Mark McM already mentioned. A year ago I was almost creamed on the SUP here in the State Forest on Martha's Vineyard by a guy coming around a corner almost out of control at about 25 mph on a electric bike with throttle, no pedaling needed. He was probably pushing 300 pounds and I wouldn't have fared well in that head-on crash.
We're a second home resort location so this is more true than many other places, but many people renting these ebikes haven't ridden a bike since they were 10 years old so their skills are lacking too.
Yesterday I was pushing hard near the end of a 4 hour ride, on the flat, and a fellow on an ebike passed me like I was in reverse. If he was speed-limited to 15 mph he wouldn't have passed me.

IIRC the Bosch unit Firefly is using is only 250W and is made for those speed limited pedal assisted bikes. I'm glad Firefly is working on making these available!

Bosh makes mid drive motors that support 20mph to 28mph, which meet the govermental regs of Class 1, or 3 ebikes

I don't know the unit on the Firefly.
It looks like an older Bosch CX unit which was their most powerful. I believe limited to 25kph but very easy to take away the limiter.
If I had that Firefly, def would have the 75nm motor and limiter gone :)

Don't like the speed limiter on your Bosch ?
Get a SpeedBox2.

Wow I am impressed by the conversation my new pedelec Firefly has received. This bicycle is using the Bosch Performance Speed motor. It is their 350 watt motor that provides assistance to 45 kph (28 mph) making it a class 3 pedelec. Before building this bike I put 2200 miles on a Trek super commuter 8+ which has the same motor to see if this was the system to go with. I looked at the Shimano system and it seemed more difficult for a small builder to use and harder to get. I also looked at the Superpedestrian Copenhagen wheel. The Copenhagen has a whole host of issues including no disc brake option and it needs to be connected to the internet to work. If your phone battery dies, your bike doesn't work.

In my 8 months testing the Bosch system I find I average around 18 mph for my 20 mile round trip commute. With the stop and go nature of it I find that I cruise along at between 20 - 24 mph. Having the head room of the 28 mph limit is nice. I think nothing now of hopping on the bike and running errands. It is faster and more efficient than the car for most trips in Boston.

I enjoy the pedelec aspect of the system. Twelve years ago I built a throttle controlled ebike and I find the pedelec system more intuitive and less obtrusive.

I really don't think I would bother if the assist limit was the 25kph (15mph) EU speed limit. I would ride on nice days and drive on others. From my research I have found one reason for this slow limit is the EU gas scooter lobby trying to protect their market share.

imo, mid-drive is the best system. Hub motors and something worse, like the Copenhagen wheel (as clever and stylish solution it is), just make the wheel way too heavy and compromise handling- they are a 'budget' or 'conversion' solution but not ideal.

Bosch mid drive is just so seamless feeling, they really have that refined quality going for it.

The bike is gorgeous, it must turn heads in Boston!

Nice Bike!
 

As someone with self diagnosed OCPD I appreciate the time and effort to get details nailed down right on Fireflys. And it carries over to the presentation, photos of your bikes are well done.

It may have been happenstance but I like the way the rear fender brace lines up with the top of the chain and again with the front fender brace. Nice bike and great pics.

As far as Ebikes go, I have been an advocate for cycling for along time and by telling people about cycling I found barriers that some couldn't overcome. Ebikes close at least one gap for some and I see it as a good thing.

It gets people out there with us who may not ever of have done it without this option. And having more people enjoying an activity we enjoy, even if it's a different way will provide benefits going forward. The more of us there are, assisted or not, the louder our voices will be for new laws and infrastructure plans.

I have always appreciated the work that Firefly puts out and I'm glad to see you continue to see cycling from a big and diverse perspective.
