Second what Thomas has said, steer clear of any of the Chinese welders such as Sunnko. The Endless Sphere forum has an ocean of postings on spot welding batteries. I recommend using the nickel strip which has small slots cut into it. The welding heads are placed on either side of the slot...

my take on a minimalist cockpit

It would be great to have a 600 W version of the Satiator. Justin is a talented and visionary guy, I've supported him in small ways since before he had a business. As I'm sure you agree, it isn't any lack of skill holding Grin Tech back. In large part, the decision to make it waterproof for...

It does have separate limits for voltage and amperage which the firmware enforces independent of the power rating of 360 W. For example, the 4808 model will never charge a large capacity 24 V nominal battery above 8 amps even though it is in an ostensibly ~200 W regime. Likewise, the 4808...

Now you've missed the point entirely. The Satiator has hard limits for amps, volts and watts. This has nothing to do with the ability to create charge profiles. These are the electrical limitations of the device. The best place to learn about this is on Grin's website, here's a link-...

I wish I were. The Satiator has a hard limit of 360 watts in all three versions. 200 Wh in 20 minutes requires a 600 watt device.

The Satiator is a fine charger, but it takes almost twice as long as that to convey 200 Wh of charge- 34 minutes and that is under ideal circumstances. Satiators have separate hard limits for amps, volts, and watts which take effect depending on where you are in the charge cycle. This speed is...

a well designed internal battery implementation will have electrical connections which are protected from water and dust at a much higher level than an external battery the Specialized Creo uses my preferred arrangement in this regard, an internal battery with a connection for an external range...

Thanks, haven't read Gibson but always liked this thought. Applies well to ebikes in general and the Creo in particular! Well said, Mr. Gibson.

The future is already here, it's just not evenly distributed.

When riding at night and meeting a car going the other way, it's nice if the driver dims their lights for you. In the last year of so, I'm noticing more cars that don't dim when approaching me. To make it worse, these tend to be the newer high-end cars with searchlights for headlights. I've...

Quick update to say that the same technique works well on CANbus BionX bikes. I've been running canbus for three months and many miles with no issues. So, yes, Ravi, it will work with D series motors as well - I believe Cephalotus has demonstrated this for some time. Krishna, I used a DC-DC...

North of you along the St. Croix, just a tributary to the mother river, but still beautiful. It was 42F here today and two hours into my ride it felt as comfortable as a summer day. Winter brings unexpected challenges, I've had rides during which ice built up on the derailleurs to the point it...

Hi Tom, not sure what you mean- advantage of what, using PF cells in winter? I only mention them as typical cells. No particular advantage to them in cold weather. Just a quality cell with good cycle life and energy density - probably why we both use them. I've had a few rides already this fall...

The attached PDF datasheet for Panasonic 18650PF cells quantifies the loss of capacity in lower temps (chart at lower left of page.) For biking at night in temps below 20F, an extension cord for the NiteRider light made it possible to put the battery inside a jacket against the innermost...

The zip tie is a clever solution. As we both found out, torque sensors involve a trade-off between strength and maximizing the flex of the part being measured. BionX measures the flex of the rear axle, which has been hollowed out to reduce the force needed to flex it. I cracked a rear BionX...

That's understandable. OTOH, the idea of a battery which is highly immune to rain and water intrusion while riding is the other side of that coin. At least it is light enough to easily carry inside for those who wish to. Likewise, if the battery only needs to be removed and installed once per...

A few thoughts after riding a Creo this weekend. This is the closest bike to my ideal as envisioned shortly after starting in ebikes 13 years ago. Just enough power to feel like a "magic bike" but you are definitely supplying as much energy as the motor with your legs. The front shock is...

Sadly, I believe NYCEwheels has closed. Like some others here, I was a big fan of Bert Cebular back in the day. Finding ebikes in your frame size to demo can be very difficult, especially if you ride a S or an XL frame. The payoff of finding the right bike makes the search just part of the fun.

There are two more Wright cycles at a museum in Dayton, Ohio. At least they were there seven years back when I was on a Wright Bros. history kick. I'd give alot to be able to ride an original Wright Cycle- at least I can dream...
