From the web site it says 1030 rpm at 72 volts 14.31 KV 29.75 m/Ohmes peak phase of 387.60. The MaxE is perfect in EVERY way except throttle response. It take a long time for amps to build from a dead stop but midrange power is pretty awesome. I’m sure that saves a lot of wear and tear on components...

I would like to see how the 72400 would works with my QS205 3.5T motor in a 17” rim. I’d probably never go over 250 battery amps but sometimes want more than the MaxE puts out now.

Looks like an excellent ride.

Tom

Super cool. You know the old saying, “Take offs are optional, landings are mandatory!”

Congratulations!

Tom

Down side to outputs being on opposite sides are then you have to run one lead way longer than the other. So anyway you look at it one lead or polarity will have more resistance than the other. I doubt there are many designs that the controller could be placed dead center of the pack keeping all thi...

The one on the right is a far better design....best I have seen and the way I have built all of mine in the last 4 years. Best current sharing...ask the pros!

Tom

That’s a bummer for you!

Hope to see you get back on this.

I think I’ll vote to go single reduction to drive. 930 or the smaller Audi 5000 CV’s work well with a lot of deflection, that’s what the Drakarts used with 16” of travel. Although if using these (read either!) in the sand the boots get eaten up quickly.....it’s how I got Indy car pitting fast at cha...

I got the nickel with the batteries from nkon https://ru.nkon.nl/ I have a MaxE and the controller limits battery power to 200 amps. Most do the BMS for charging and balancing but I think discharge protection is a must but I’m not for sure. The one that “CyklonEbike” uses looks to be a good one with...

I’m interested in this project.

Tom

On higher current draw stay away from the strips....too small in most cases and then by adding a double or triple layer just increases the resistance. Go with wider strips that can carry more amperage and takes care of both parallel and series connections. Then add copper to the top of the strips fo...

Looks like a good design to me.

Zero buyers remorse.

Some sort of underlying pun intended here? Was that an actual statement from you or was it a dig at those who bought a Zero?

Pretty sneaky buddy, pretty sneaky!

Tom

Looks good to me but always about the bicycle components since I’m a 6’ 4” 210 lbs guy? Us bigger people are hard on things due to our size.

I’d love to have a lighter bike I can peddle at speed. What speeds are you getting out of this?

Tom

Nice review Rix.

Tom

I’m not sure how less amps could make more torques unless the MaxE was not properly tuned or the shunt was improperly set up?

Selling my green SurRon. viewtopic.php?f=9&t=96733

Now that I own an Alta EXR, I don't ride the SurRon anymore.

Excellent! When is the ride report coming?

Tom

I’d say proof is in the pudding......the Sur-Ron sure “looks” fast!

I’d do one of these in a minute if they had the Adappto “full meal deal” of BMS and charging.....it’s just so convenient.

Tom

Very impressive Adam. Congratulations on a huge win!

Dorado if night and day better!

They came from the Netherlands and took about 3 1/2 to 4 weeks to get here. Total cost was right under $1300 shipped to my door for 305 cells, a shit load of nickel and a shit load of insulation paper. The pack is good for a speculated 100 miles at 20 mph. I was able to go 35 miles and used 34% of m...

Super cool build.

Tom

Battery is sold....sorry forgot to mark it sold.

Tom

You do see the 2 strips of 10 gauge copper on each positive and negative nickel strips don’t you? Soldered to the nickel in between each of the cells with silver solder? It’s my opinion that running multiple wires to many spots vs solid copper wire soldered to each spot is either the same or better ...
