Finally some good content on these, can't wait to pick up a similar model

[@beastmode207-fq6jq]

This is identical to the E strapz 12k watt in black. The 15k watt has a 75AH battery!! I'm getting one next week. 70mph bike. I went for the 4 tooth for speed And torque.

[@rolandroland1485]

What are you talking about ?! Those are 2 different bikes You are you are referring to is a stealth bomber clone which has a bigger battery compartment, the cs20 can only take 50ah Plus they now have a mid-drive version

[@steven1498]

@@rolandroland1485 th e-strapz cyclone mk2 is the CS20 with a few upgrades 🤑🤑🤑

[@1ChocolateOnyx]

Cool video 👍 These CS20's are underated. The usb module is to tweak/customise how your bike performs so you can tune the 150a controller so your bike goes 70 and still have all that torque. Plus reduce any throttle delay.

[@STFOURNARIS]

Good to know for i was under the impression it was to connect to the phone and show you details of the amp consumption and details like that. thanks for watching

[@rolandroland1485]

How ?! What parameters do you have to adjust on the sab ?

[@michaelbuteau4183]

That bike looks like a lot of fun when I was looking at bikes I thought about getting one like yours or an onyx and I was looking at a few other ones but the rear hub motor scared me I figured on the Arizona desert Trails I would just beat the motor to death so I ended up with the Surron and I really like that bike I have a blast on it and I modded it so much it's barely even a Surron anymore great video by the way your attention to detail was great

[@steven1498]

Please let's see a update and a maybe a other run on youre bike thanks man ! this one was good .

[@thetechgenie7374]

You sure able able to get faster then 45mph with that controller. Likely current is set at 50 amps but if Samsung cells and controller outside you sure be able to push over 100 amps

[@STFOURNARIS]

Yeah i might have to look in to that. Thanks for sharing that information

[@paulmryglod4802]

​@STFOURNARIS it's the 5t winding limiting speed. I have 3t, 3.5, and 5t and as long as there's enough juice, ove 100 amps, they'll all reach top speed.

[@kebikes3650]

Yo bought a 15000w one, with a 3.5T motor (for top speed) and its coming in 2 days. Super excited to see how it performs and how much torque it has with a motor geared for speed. (hopefully a lot lol). Its running a 200 amp Fardriver controller and does not come with the wires to program it or change anything like your sabvaton controller does. Its basically the same bike as yours but pushes a ~3600 watts more power (nominal) and has a bigger 72v58ah battery, paid $3300 total

[@STFOURNARIS]

Man that is a good deal. I hope you make a video and update us on this one

Hey @kebikes36, how about an update on your experience and where you purchased with the modifications! Tia

[@kebikes3650]

@@OB1kyote64 The bike is pretty decent overall, some things I would change, and I would advise not buying it. the speed and power is incredable, and the bike is wicked fast, the frame is just a bit too small for my size, at 6'1. battery life is great, the controllers are sent undertuned, and the bike is pushing less power than it has the capability to. the components on the bike are cheap (that arent electronics), most parts are thin cheap plastic, my kickstand broke, key switch mount broke, and more. the rear light setup is terrible, and when you bottom out the rear shock the light hits the back wheel. the suspension is alright, but you need to get the upgraded KKE fork and DNM Shock. Its not good offroad at all, lots of screws come loose really easily, and the hub motors are terrible offroad, and are prone to breaking hall sensors, making the motor not work at all and either spending the day fixing and soldering a new one back on or buying a new motor (expensive or time consuming). If you plan to buy this as a off-road bike. Dont. Its pretty good for road riding, make sure you get street tyres. Make sure you get extra tires, and lots of extra brake pads, and cheap parts. pretty good for the price, but you will have to eventually upgrade a lot of the cheaper parts over time to make the bike really reliable and comfortable to ride.

most sabvoton 200

[@minde28383]

it disconnects basically on big bump, There is some connection issue in wires. It happend so many times for me on certain ebikes. So i know it is wires or battery wiring etc connection. It disconnets, controller reboots so and after few seconds you good to go.

[@STFOURNARIS]

Thanks for sharing that information. I was under the impression that it was a safety but i guess not!

[@chickenrichard5024]

Battery working at 167 amps is how you get to 12000 watts at 72 volts. Probably need to go into the sabvoton using the connected app or plugging into the controller and seeing what stock config they laid out. I have an 8000 wattt I just swapped out to work on my next project and that easily cleared 40mph with the qs273 5t motor with a bit of Flux weakening. The sabvoton being 150 means you can't actually get to 12000 watts sadly

[@chickenrichard5024]

You'll want to change the sab to either a 200 amp unit or convert over to the ASI BAC4000/8000. The motor is absolutely phenomenal, and they are pretty easy to modify up to where they need to be. You'll want to enable maximum Flux weakening for higher speed. You also want to see what your amperage settings are for actual draw and phase amps, as well as how regen is configured.

[@rolandroland1485]

@@chickenrichard5024all this sounds good but you need to check the battery maximum amp output ?! Looks like the battery is limited at 150A, anything higher might shutoff the BMS

[@williambontrager2349]

I almost bought one of these bc I love the design. Ended up going with a standard Enduro frame 7000 watt version bc I had the option of getting a 72v 60ah battery...and a fully carbon fiber frame electric motorcycle.

*I hear ur front fork banging, losen up the handle bar neck n tighten the top bolt first to pull forks neck tube tighter that’s how I got mine quieter, the shock u can adjust almost all the way stiff n back off very slightly n it rides better, 20-25lb air n helps as well* I put a Enduro seat on mine wider 100x more comfortable ( I had to make few easy mods to make it fit

[@STFOURNARIS]

I have looked for that valve you mentioned and unfortunately on this model I didn't see any way to add air. I turned the top turn nub two clicks from max stiffness to stop the long bolts from hitting the tire all the time so my front is not as soft on landings lol.

[@CaptainCurt07]

Should be adjusting knob on rear shock and front sweet spot is all way closed then open 1 click at time or you’ll miss it, front fork should have valve on top n bottom, my rear shock is night and day finding that sweet spot

[@dust6242]

Needs a 200a controller 🥱

[@STFOURNARIS]

LOL honestly i thought the bike is good as is and that's because I've gone up some steep hills that it had no problem climbing but not that it cant use more power i mean more power is always good to have when needed. One thing forgot to mention is the breaks, both have a safety shut off when pressed and i do recall having to stop on a hill to avoid hitting another rider which got me in to a pickle lol and with that said I've been thinking of disconnecting that rear break shut off.

Wow!, I did front pads around 350 miles and back around 400 miles. At 100 miles ! man that is very low miles which makes me wonder what pads where you using so i can steer away from them. The originals where OK but the new ones i installed where given to me by my brother that are supposed to be the Surron stock pad. i did order 20 pairs from the manufacture which i got the bike from when i ordered my sons bike (CS20 5KW 72v 41.6ah Samsung battery) for few hundred dollars cheaper then the 12kw.

[@beastmode207-fq6jq]

Shoulda just got the 15kw. You're gonna want more power.

[@HD-eu3zs]

How does the torque feel compared to your modified 5kw razors? I was under the impression that hub motors are better at top speed and road riding, but lack the torque for climbing steep mountain trails. Thanks. Hoping you'll do a trail/enduro video.

[@STFOURNARIS]

They feel very similar on the torque with only size been the deference. They both have wheelie power on slow speeds and get gassed out quick. I like both of them however the small one feels more stable due to center of gravity, the CS20 is very heavy on the rear and the off road tires when inflated over 15 psi tends to rubberban the rear end. When i lower the PSI to 13 it runs much better however due to the lock of tire lock i keep reaping tubes so i now roll with 18psi as i am getting tired of changing tubes.

[@dennis_503_gutierrez]

Great video. Thanks for sharing. I was wondering how it would ride off-road since I use mine to commute to work. My tires are different and probably the motor too. Also, where did you get those lights? They look cool .

[@STFOURNARIS]

I just added the link in the description

[@0xsergy]

from what i read about hub motors on ebicycles is that wheelspin is bad for them. if your offroading is fairly moderate you'll be fine. any crazy inclines and such(for extended periods) will likely burn the motor out(but i'm just guessing, maybe these ebikes have better hub motors)

[@dennis_503_gutierrez]

@@0xsergy it might be true. This kind of hub motor do get warm after riding for a while. I ride to work about 50minutes none stop at 45mph+ and motor does feel warm when I get to my destination. I only stop at red lights and stop signs. I put 5k miles already and so far it still working. I guess if you abuse them hub motors they will burn up..

[@STFOURNARIS]

@@0xsergy So far i have taken it to some steep climes and have come to a complete stop and the motor is able to push my weight and its own. personally i think this motor is so big compared to a qs205 that i cant see it burning that easy. It gets worm when i take it to abusive rides but haven't noticed it getting hot or anything so far, i cant speak for the breaks though i did check them and the were scorching hot lol.

[@thetechgenie7374]

Those kickstands are junk. I broke the first one as well and started rubbing on the tire. I ended up getting the revised kickstand which is a little better.

[@panosmamoyzellos3924]

Nice video!!!! I love this frame!!! 5T hub is better on dirt and 3,5T for the road i thing. Also there is a lot of potential to make it go faster if you want, the frame can handle more power!!!!

[@0xsergy]

nice simple frame. square tubing isn't as strong as circular but my Himalayan has similar square tubing to this and it weighs 430+lbs so if the welding is okay this frame should be plenty.

[@STFOURNARIS]

Honestly the torque on this has chewed every crazy hill i have thrown at it. When i got it all i had in mind was high torque and this 12kw qs273 is very impressive on my book.

What a strange bike. Its like a stealth bomber clone but weird

[@CaptainCurt07]

*I got same bike and exactly same issue, kickstand broke very easily, swingarm very lose ( how’d u fix that?) check ur hub motor cable it’s extremely close to hitting rotor, I took the washer from behind rotor out gives more clearance, please advise on swing arm fix*

[@STFOURNARIS]

I used a large allen wrench and just tight the screw as much as i could. At some point i thought i might end up stripping the screw or something but it all worked out and i do check it from time to time. My display just gave me error 10 and after checking the cable that goes through seems to have an issue and i need to fix that (530 miles first electrical issue ) all though i wouldn't consider it a major issue i do have to disassemble the rear end sit and get to wiring, pull cable out of the hollow frame and figure a way to fish it back through (Most likely attach a line when i pull it out to help me pull in back in place)

Does the pedal assist work I have one on level 5 I can only get it to 5 mph

[@STFOURNARIS]

It did for me, 1-5 each has different top speed. Do you have the same sw900 display? if so i would think the one you have may be defected unless the sensor is not working properly, on the left pedal there is the pedal assist sensor from what i noticed on mine. This bikes are hard to work on due to the cables running through the frame and the heavy hub.
