Re: new eZip motor

Perhaps a properly connected and shrink wrapped 6 x 36V 4.4Ah hoverboard battery amalgamation (36V 26.4Ah)? His 36V 500w motors should never even draw 1C, ensuring extended lifespan. I love the little hoverboard packs! (mostly because I got such a bargain on genuine Samsung builds) Typically charge...

Re: Fast Ebike for a tough commute

Look guys, we're talking past each other. The OP said he wanted top speed of 35-40 mph. He route has lots of hills. I'm talking about going downhill. wturber's talking about everything except going downhill. When someone talks about top speed and doesn't otherwise qualify things, the assumption is ...

Re: new eZip motor

Save your money and buy all packs at once and parallel them together from the start. A little patience and planning goes a long way.

If you can afford to buy new packs, then you should be able to afford a y-cable to combine your Sona and Samsung packs in parallel.

Re: Bicycle Speakers

.........Anyway, I agree. Vision and alertness trump hearing by a long shot in my experience. So is listening to the traffic around you when you ride is not alertness? Alertness is a mental state. Listening can only be a very small part of alertness because the amount of information it provides is ...

Re: Bicycle Speakers

The amount of noise a single modern vehicle can make, (at a distance where you'll actually have time to hear it, look at it, find a path to evade it and react accordingly), is generally going to be well under the noise floor created by the general din of traffic and other city noise, as well as win...

Re: Fast Ebike for a tough commute

Anyone saying that you need 1000W to go 40mph must be sitting straight up and riding like they're on ape-hangers. Grin's motor simulator says that the load to go 40 mph on a full recumbent is 978 watts. A road bike set up for commuting is very unlikely to be that slippery. The simulator gives a loa...

Re: Battery capacity issue or not

Have you measured the discharge? What are you using to measure the charge amount?

There is a lot of fraud with batteries from China - especially individual cells.

I'd try to measure performance a couple of ways before coming to a conclusion.

Re: Removing speed restriction Wisper 905

I believe you can get Wisper to remove the speed restriction but you will need to sign a disclaimer forfeiting any warranty you may have. If there was a sequence to get into the service menu settings it would be difficult to guess it.... Maybe. OTOH, there are only three buttons on the LCD controll...

Re: Best. Headlight. Ever. Taillight, too!

My bike configuration is significantly different from yours. I mount my headlight to a piece of thin plywood that fronts my front basket. I use simple L brackets from the hardware store and also drilled through the fins for the mount. But I don't recall removing any fins. https://endless-sphere.com/...

Yep. I've been running one for over a year now. There are now some other variations and some with a daytime Halo feature that would be worth looking at. I just use a standard 12 v dc converter from my 36 volt batteries and a three-way motorcycle switch (on-off-on) for high-off-low. XT60 connectors. ...

Re: Removing speed restriction Wisper 905

It seems like the limit is software driven. So getting access to that screen is what you'll need to do if the idea is to keep the bike otherwise stock. My KT LCD5 has a similar setting and it simply monitors the motor rpm - converts that to speed based on wheel diameter, and cuts power when the spee...

Re: Critique my plans for my first build!

DD hub motor for a durable, low maintenance commuter is sensible. It will need pedal help up hills steeper than around 10%. It is good to err on the side of an oversized battery IMO. The same brand freewheel on my similar kit was pretty much junk. And I'm fairly tolerant of mid-quality stuff and not...

It's a long shot that this would be helpful, but in those rare cases where a bike is recovered, listing on a registry like this one might be useful. It's worth a shot considering the super-low cost. https://bikeindex.org It would also be nice if you are buying a used bike to to a pre-check. I only h...

Re: new eZip motor

I made it back ok but definitely notice sluggishness in the Samsung packs maybe even more than the SONA packs. I pedal assisted up the small hills. Not a lot of steep hills here in Central Ohio. I will need to order a new battery pack this month if I don't make the trip to NY. I would like to start...

If legislators treat that as the norm,...

Re: Looking to build a bike

As a general rule, you don't build an ebike to save money. You might end up saving money in the long haul, but if you don't totally ditch the car and insurance, you won't save much. If you really want a car replacement bike, I think you need a long or medium tail that will allow you some space to bu...

Not necessarily. Which Bafang motor do you have?

The 20 inch wheel could be a limiting factor.

Re: Advice about a motor upgrade

The motor is a direct drive motor - it is a 9C (nine continents) clone. It should be very reliable since it has few moving parts. It is the same kind of motor that I have and I'm nearing 10,000 miles on mine. Reports of 20,000 miles are not unusual. As for the speed, the problem I see is that they d...

You might want to double-check your measurement and make sure it isn't 6 5/16" as opposed to 6 5/8". Better yet, use a ruler with metric measurements.

Re: new eZip motor

Nothing but is 168.25 mm. If I get a 160 mm It should work. I located one at a bike shop for 20 bucks. I just need to go there tomorrow and pick it up. Thanks. LC out. I just measured one of my old Shimano 160 mm discs and it is very close to exactly 160 mm. So there's something very odd about that...
