Any Factory members into electric biking? I recently traded in my conventional 24 speed Giant bike for a Gazelle Arroyo e-bike with a Bosch electric assist motor. I ride mostly on urban streets, paved trails and packed limestone trails. As I get older and experience shortness of breath and generally decreasing stamina for endurance, I found myself avoiding hills, long rides and windy days. My worries about getting stranded have been mostly unfounded, but sometimes stopped me from going as far or to places that my riding partners wanted to go. So I am hoping the e-bike will actually give me more exercise by increasing my confidence to ride more often and on longer and more difficult trails.

The Bosch Performance Line motor is mounted on the crank. It still requires you to pedal at all time. There are 4 levels of assist that increase your peddling power from about 50% to 260%. The maximum speed is 20 MPH. The battery range, depending on weight, wind, terrain and assist level, is from 25 miles up to about 90 miles.

So far the only ride I have taken on the Gazelle is to the drug store to pick up a prescription ... about a 10 mile round trip. It sure was fun being able to kick up the assist when coming to a hill or heading into the wind. I hope the weather warms up soon so I can get it out the the trail and give it a real test.

My wife has an e-bike that she bought last summer. Hers is a Blix Aveny which has a hub mounted motor with a throttle, so you can actually ride it without peddling. It also has a max speed of 20 MPH, but the range on battery is considerably less (15 to 35 miles).

On my old Giant bike that I traded in, I had my Garmin Oregon 550 mounted on the handle bar. This not only told me where I was on the trail map, but also gave me a speedometer, odometer, trip distance, elevation changes, etc. The Gazelle display has its own speedometer. odometer, and trip meter, but I will probably still use the Oregon for the map and elevation. It is too bad that Bosch doesn't include a GPS chip and barometric altimeter in their control system.

I would like to hear about the experiences other Factory members have with e-bikes.

I have no experience with them yet, but I want one. I'm waiting for the prices to drop a bit.

May Be Quite A Wait

That may not happen anytime soon. Their popularity and short supply may last well into 2022.

another fire

Here is another fire caused by e-bikes charging:


oh oh

New York's nannys will be banning them pretty soon.

I never get lost, but I do explore new territory every now and then.

Banning? maybe, maybe not

All the important laws about buildings in NY State were passed after fire disasters in NY City from a century ago to the more recent.

E-bikes could be next.

NY State Building Code
NY State Fire Prevention Code
NY State Labor Law

All three passed in the aftermath of the Triangle Shirtwaist factory fire:


NY City Local Law 3, regarding the construction of office buildings, especially high rise office buildings.

For the first time, fire sprinklers were required for most office buildings. This law became a model for similar laws in other cities, and across the US. Passed as a result of the One New York Plaza fire on 8/5/1970. This building previously had no fire sprinklers.

another lithium ion battery fire

Another lithium ion battery fire in New York City, likely caused by an ebike. It was in an exclusive area of Manhattan.

New York City Fire Department members performed a roof rope rescue on the 20th floor (200 feet in the air) in which firefighters rappelled down the outside wall of the building and lowered a woman from the fire floor to the safety of the floor below the fire. Many people were injured.



A previous fire:


Lot of offers

In the nice park at somewhere recently, got lot offers to have e-bike while it last in policy

seller said you need to buy it before new laws applying smile

asked him how much for e-bike made in china, then he said it's from 1600$ up to 3000$ depending on how much power you want to get and battery is lithium

while it's so funny and especially I don't have enough money as before to spend on it, then just smile at him and said:

Enjoy before it limited" in meaning

Yep laws coming soon and meaning you have very limited option while it last

enjoy and be happy!

yet another e-bike lithium ion battery fire

Another fire in a New York City pizza restaurant that was caused by charging an e-bike overnight:


Responsible E-Bike Owners..

Do not charge lithium batteries unattended!

Have a smoke detector and stay within earshot. This buys time to intervene should a fire start.

Keep an appropriately rated fire extinguisher nearby.

Charge outdoors or in a separate structure away from living space. if this isn't possible, charge batteries on a dolly on a concrete floor. That way, the dolly can be pushed outside with a garden rake if a fire starts.

If e-bike owners followed just half these precautions, we wouldn't be reading about all these battery fires.

Stupidity and the lack of common sense is the root cause.


I have been riding the same bike for almost 40 years. Old Hard Rock mountain bike. I now have it converted to street tires, no more knobbies, and a more comfortable seat. I ride the forest preserve trails for about 10 miles everyday. The Chicago area has great forest preserves with trails. Can ride almost unlimited miles through the forests without having to cross a street with cars. Recently I have seen an influx of some massive ebikes that look more like motorcycles riding the essentially level trails. I just wonder why? I can see if you want to commute to work, or go to the 711 or some such thing, but scratch my head when seeing these behemoths on the trails that are used for walking/running/bike riding for exercise. I just try to stay out of their way as a lot of the riders appear to be new to them and not under complete control.

The e-bike marketplace is new and competitive with manufacturers jostling for position in each price band. My suspicion is that engineering the charging electronics to a cost is the likely root cause.

Tesla figured out at the beginning of the company that they could not buy cells with a zero dangerous failure rate. So they took a lot of care and expense to use an assembly which isolated the cells enough from each other that a single cell failure would not usually propagate.

The reward is that Tesla battery fires, while they get a lot of publicity, are over an order of magnitude less common than are engine fires in Internal Combustion Engine cars.

Boeing learned this same lesson in service with the 787. Plenty of others have not learned it yet.

cell separation in Teslas

I thought that the cell separation in Teslas was to permit the liquid coolant that would in turn permit rapid charging. (Obviously there can be more than one reason.) Rapid charging without serious battery degradation was a marketing requirement. This is one of the few times that I am not offended by marketing requirements.

EV fires get publicity because they are spectacular and we're not good at dealing with them yet.

Do e-bike batteries even have thermistors to partake in the charging regimen?

Some reviews of e-bikes

Pennsylvania just passed some ebike laws for state property
