Could you tell me the size of the rear shock on the mgv3 I'm thinking dnm burner... Was hoping you could help out... Thx for all the content

[@maximumchargeEV]

@@shenanigan3083 not 100% sure on that one, I would check with customer service they will tell you with more accuracy than I can

[@shenanigan3083]

[@PathtoYahawah]

Can you do a review on the Ridstar and compare it to the MotorGoat V3? That would be awesome to see its stats comparison.

[@maximumchargeEV]

@PathtoYahawah I already know the motor goat would crush it. No review needed.

[@rufusirvin5279]

You can put a Grin ALL AXEL motor that is thru Axel. They are coming out with a high power Fat ALL AXEL very shortly . I pre ordered 3 originally designed for pushing 32 - 36 foot sailboats replacing a 12 hp diesel motor. With Statorade.

[@maximumchargeEV]

True. Front motor compatible? Cost?

[@WyomingRider]

That bike is crazy powerful! Great job!

[@maximumchargeEV]

Thanks man! Yeah the front motor around turns is sketchy af

[@WyomingRider]

@@maximumchargeEV I bet lol.

[@EBikeBuilder_]

Very cool! Great to see an update on the Psycho Cycle! 20:30 the wobble is from flat out , in the vee speedster style tires, i had that problem with flatout in those styles tires too. I got arisun big smoothy tires and i don’t have that problem even with flat out. And knobby tires i don’t usually have the flat out wobbly problem. So it might just be those tires!!

[@maximumchargeEV]

After I made the video I realized that yeah it's probably the flatout, I actually sometimes get wobble in rear tires of other bikes when adding flatout and running the wheel full speed no load. Maybe I'll fix it, it's a work in progress for sure! Thanks for the comment man.

[@WyomingRider]

I learned a lot upgrading my Power Goat!

[@maximumchargeEV]

Good stuff!

[@MickyBee73]

[@heavyhitter8972]

Nice work on the video and building that BEAST of an ebike. I have a Five Star and would like to know if your Five Star feels any less powerful after overheating it in that last video you made. Thanks

[@maximumchargeEV]

I still have to ride it after that last ride. My guess is that it will work just the same.

[@shakeymikesadventures6793]

Just to let you know, if you are running both controllers sharing the battery, you can share the same signal wire outputs from the throttle,and the p.a.s.. I have made 2 so far dual direct drive ebikes, one is on my y/t page that i made from used parts. twin 40A controllers on 48v sys , 1000w rear,1500w front. the controllers are the kt series and are rated for 48-72v 40A, with shunt mods.

[@maximumchargeEV]

I specifically wanted two throttles for more control. I don't want 2400 watts in the front motor around corners.

[@z3r0x456]

Awesome build!

[@maximumchargeEV]

Thanks!

[@psychotropic28]

i think you should introduce dual motor on the motor goat. thatd be sick. i just purchased the goat v3. love your channel

[@maximumchargeEV]

Lol someone else can build that. I'm going for a high power single motor on that one

[@Ebikepowelevel5]

Great video as always thanks for the shout out I think you should definitely build the five star I a going to put the kit on my new step through and I plan on using the 60v battery in the back for the front motor we can compare times

[@maximumchargeEV]

I almost didn't know who this was until I saw at times you had your old youtube name haha. Looking forward to seeing how your build comes out!

[@charlesdavis124]

It might be the flatout in the tire thats causing the wobble. I put a stabilizer bar on the front of my bike and its like night and day. Get one for that bike!

[@maximumchargeEV]

I think you're right because I'll put flatout into other bikes and it does the same in the back there's more wobble

[@Trailtested]

Yo Max, I'm excited to see you upgrade that ecells since I want to do the same thing with my freedom. Looking forward to it.

[@maximumchargeEV]

Still haven't decided if I'll go through with it but maybe! Just need to research of so much weight on the swing arms will make the suspension not function well you know?

[@somewhereintime8742]

@maximumchargeEV Oh good thinking, man. I just don't even know where to start with planning and the safety considerations of the whole project. And like you mentioned in the video, I don't know how I feel about having all of that weight on the back.

[@blown9646]

Very nice, tastefully done. Ps, you can get a 21700 20ah pack from ali for like $240. Wow, looks like two indentations both lower sides on battery from shock smack on that 17" frame. Bummer

Yeah but what type of 21700 cells will they use? Also that battery is fine no indentations

This video gives me an awesome idea. I bought the minimum necessary (while being careful to buy the style that can be upgraded/modified) because of money constraints. In the future, I may add the same front wheel setup!

[@maximumchargeEV]

Hell yeah man! Looking forward to seeing your build

[@TylersTrailRides]

I'd love to line up my new talaria next to it. 6500 watts rwd vs 5400 watts awd

[@maximumchargeEV]

That would be fun!

[@nemohunter87]

thanks for sharing about the bike. What kind of forks are those? I've used rst guide forks for awhile but wouldn't mind checking that one out aswell!

[@maximumchargeEV]

Those are from a company called smlro they make dual motor forks. They could more easily accommodate the larger axle of the 1000 watt motor vs the rst guide fork which is only good for 750 watt 10mm axles

[@Mikehud1984]

Just ordered a Five Star on the 4th of July. I will likely be adding a front motor or upgrading the rear at some point.

[@maximumchargeEV]

Hell yeah! Make videos! Where will you get the front motor?

[@Mikehud1984]

@maximumchargeEV Not sure yet, I was thinking of going with Powerful Lithium for a custom battery, but now that you mention Northeast Battery Systems, I'll have to check them out. I'm also in New England, so I'll be watching your videos for build and parts ideas, lol.

Tried my best! Thanks man!

[@140theguy]

You realize they make a rear rack that holds a battery under the rack? You did a decent job at camouflaging everything but the triangle batteries almost always look ugly. If it's the fastest thing on the block who cares what it looks like. 😎

[@maximumchargeEV]

Yeah but it can't hold a lot of capacity, maybe 15 amp hours? My secondary one is almost double that

[@140theguy]

@@maximumchargeEV they make 72v up to 20 AH and 60v up to 30AH. I know places like powerful lithium can make you whatever you want.

[@maximumchargeEV]

@@140theguy link me a rear rack that can hold a battery that size inside the rack itself. The cases and racks have to be on aliexpress somewhere..

[@housedjnyc]

Have you considered eliminating the front throttle and display by just running a signal wire from your front controller to your rear throttle?

[@maximumchargeEV]

Front throttle gives more control and is way safer than running both motors on one throttle, and I like being able to adjust from motor power levels If needed so I wsnt that display there you know?

[@housedjnyc]

[@140theguy]

Grinn technologies makes motors for through axles.

[@maximumchargeEV]

True. Cost? Front wheel compatible?

[@140theguy]

@@maximumchargeEV all I know is my buddy used thrir 2K direct drive Motors front and rear on his 26-inch bike. I believe he's running 2K to the front wheel and 4K to the rear wheel at 72v. That's about as much as you can put To The Ground somewhat safely.

[@MrCsebike]

I have a question. I'm trying to get stuff for my first build and I don't know if things are getting lost in translation, If I have two batteries in parallel both with a 50 amp BMS does that meen I can draw 100 amps or is it still just 50?

[@maximumchargeEV]

In theory yes

@@maximumchargeEV Thanks, the Co. I was trying to get parts from said I needed to stay with a 45 amp controller when I said I wanted to run around 60 on a 80-100amp.

[@oldmanebikes8392]

Nice work. You know I have your 5k motor sitting here if you need it. As long as you can fit 100mm rim in that frame and it looks like you can it's not a lot wider. But it's brand new in the box grab it before I send it back. I think that bike will rock with it.

[@maximumchargeEV]

I'll think about it! Still in the "should I do this" part of the build. Idk how well the suspension will function with the weight of the battery on the rear rack you know?

[@rufusirvin5279]

​@@maximumchargeEVthose step throughs cannot withstand the torque and weight of putting any high power motor into it. Before you do a faceplant get another frame. Maybe you can get someone to Tig a crossbar over top of the battery.

[@maximumchargeEV]

@@rufusirvin5279 I think he was talking about me putting it on the ecells bike like I said in the video

What are you using to connect dual batteries and dual controllers? Ive been trying to find a dual battery balancer that will allow this

[@maximumchargeEV]

i connected both batteries to a battery balancer/blender (generic from aliexpress but rated for 100amps) and the output has a Y splitter that goes to each controller.
