One other thing to note based on the simulator is the 1000w and 2300w are nearly identical in efficiency / range at the same constant speed, which make sense as it take the same power to go the same speed and the motors are identical except for software. So unless there is some other factor not...

In hopes of trying to get a better understanding of how big a battery I would be happy with on a Hydra and just have a better understanding of its performance with different wattages and gear ratios I attempted to simulate a Bafang G510 with Archon controller on Grins motor simulator. From what...

Yes a good dual battery option gives a lot of flexibility. Also how about just offering two integrated battery options? One with the lighter 21700 config and the other more expensive 18650 config with more watt hours? Maybe even a new 21700 config with some sort of bump out with higher watt...

Yep if you do the same route all the time and wind nor temperature changes much you can really tune the watt-hours needed to the bike you use and not carry any extra. I know for me I have a usual set of local rides I do from my house and it pretty consistent in battery use, however had a couple...

The problem is the amount of watt-hours need for a certain butt-hours varies significantly based on terrain, speed and temperature. So there is no simple way to account for that other than having much more battery than you actually need most of the time. In an ideal world I have a 50 pound...

Thought I would use my throttle more on my current bike but pedaling is more fun, still very useful for quickly getting across intersections from a stop and the similar situations where its difficult to get pedaling from a stand still.

I agree 3 hours is about all I can comfortably do currently with a nice seat and Kinekt seat post and hard tail with fat tires, but that is 45-60 miles at 15-20mph and my current 996wh battery is sagging pretty bad by the end of that on flat Florida trails in warm weather, 16wh/mi eats 800wh for...

My thoughts are if the stock throttle is too touchy (on/off) as Jayaznpride has reported then yeah shifting would be a bad idea, but if it where more controllable then you could do it more safely you just don't have the feedback that your feet do for giving just enough torque to spin drivetrain...

Looks like an Eggrider which I think would be a good option for Pushkar to offer I would probably go for it although I have heard its not very readable in direct sunlight.

Just looks cleaner too based on some other pics you posted. Shame about lacking eco/sport I would prob program it with 1-3 being 750w equivalent of 1-5, 4 would be 1000w 5 equivalent, 5 would be 2300w full blast. My Juiced RCS just has 5 levels and its fine, 1-3 seems to be class 2 pretty...

1700wh would be 32ah at 52v right? 16wh/mi would be great, I have to hold back and conserve to get that on my Juiced. Problem is you never get 650wh out of a 650wh pack and its not great to run the battery to 0 nor is it much fun, I get noticeable performance drop off once my pack is below 48v...

40-50 miles is usually the most I want to go, however the really has to be qualified with how fast and the terrain etc. So I guess the question is what does the Archon get in wh/mi at say 20mph on flat ground on a Hydra? My current bike is a Juiced RCS with 996wh battery (52v 19.2ah) and the...

Funny because its the downhill bikes that seem to have coil springs vs cross country having air springs. Goes against what I know of air vs metal springs in cars, "air ride" being better for small bumps due to the progressive nature while coils are cheaper and less maintenance and more robust to...

Yeah for me most of my day to day riding is paved, but I like to mountain bike. Like the idea of a "SUV" bike that can do it all without having to change tires, Johnny Watts are getting good reviews for exactly that...

Really interested in how the 500c works, not a big fan of giant cell phone sized display in center of bars, thats where I want to mount my cell phone! Don't need two cell phone sized displays. Would rather have minimal built in display and app on phone for more details and Nav etc. Really like...

Does Schwalbe even make a 3.0? Its not listed on their site. Also great looking tires how noisy are they on pavement? I would probably do the Johnny Watts, less noise / rolling resistance and ok off-road but they also only seem to go up to 2.8 as well.

If you want to see and learn what a charger does with respect to current and voltage Grin has a great charger simulator (they also have a great motor simulator as well). Again no BMS I am aware of will do this. Here is a 52v 85% charge profile at 5 amps...

Again that is no different than any typical "smart" BMS I have seen unless I missed something, he even says in the beginning of the video "the purpose of the BMS is to protect the battery from critical events" it also does passive cell balancing which is a different topic but important for...

BMS are protection devices, they will turn OFF or ON based on voltage or current. They will protect your battery from overcharging or over discharge. They have either relays or in the case of most bike solid state mosfet switches that are either on or off thats it. A CC/CV charger can hold a...

Would be interesting to know how the "smarts are going to be moved into the battery", that basically means the constant current / constant voltage "charger" will be in the battery if its going to control SOC which is just the constant voltage held at the end of charge and the bulk charge current...
