[@anthonyfogleman8652]

@endoprysmyt you didn't properly mount your rear wheel, over time you will ruin the drop outs of that frame

[@lukewalker1051]

I have two BBSHD bikes and no rear hub drive ebikes. My BBSHD bikes with 52v batteries will top out at 40mph. Would be great fun to have more top end but of course risk is elevated as you state as mtb's aren't designed for higher speeds. From someone that has built a lot of cars, motorcycles and ebikes, what you describe as 'sketchy' is what makes something fun albeit with risk. Riding on the edge. A more solid aka competent chassis makes the riding experience more serene. If you drove muscle cars of the 60's this is quite apparent...weak chassis and brakes and bad tires. Thanks for sharing your talent and build with us.

[@ChasingCalibasses]

I have the bbshd as well I want to go with high voltage but scared to make the jump but more power would be nice

[@Full_Throttle_no_Brakes]

For everyone building any electric vehicle. Never use that yellow wiring block. The wires get too hot and will melt plastic. If don't catch it on time, it will short your battery with. Motor phase wires with the full voltage of battery, damaging your motor, damaging your battery and can cause a fire. Please do not use that yellow block. Just get copper washers, tight that bolt and use isolation tape around the connections. That torque arm is not recommended for 3000w, only up to 1500w ma . You need a much longer, stronger and made of stainless steel to hold the motor in place. That frame is not recommended, because as you can see, very little of the drop out attach to the motor, research a more appropriate frame for such high power with reliability. For the purpose of the video, it will work. Great build man. It gives people the basic to start, showing that, It's not that difficult. Cheers!

[@memesquad9608]

you must be fun at parties

[@ChrisBFerguson]

Wouldn't heat shrink be better than electrical tape or use both? I couldn't agree more with you about that torque arm. I have two custom torque arms on a 1200W Ebikeling conversion. One on each side. Cost almost $300 but strong as hell stainless steel and no hose clamps because they bolt into some extra rear rack holes. I think this frame is fine (except lack of rear rack bolts for torque arms and probably only supports 160mm rotors) considering the motor is 135mm and not 150mm but this motor is definitely the most hub motor powerful you can get on a pedal bike frame.

[@Full_Throttle_no_Brakes]

@@ChrisBFerguson Just remove the block, get a short bolt and nut, tight both wires together and put isolating tape around it. Copper washer is just to make a better contact but not strictly necessary

[@ChrisBFerguson]

@@Full_Throttle_no_Brakes Yes I understand everything including the part about the copper wash but wouldn't heat shrink work better than tape and also look better too if it's the same color as the connectors?

[@Full_Throttle_no_Brakes]

@@ChrisBFerguson Yes, it would be much better but not everyone has heat shrink

[@anthonyfuentes1179]

Bro you deserve more credit than you get. Been watching your videos for a while now. Also yea I been wanting to build a bike like that for a while but can’t afford it yet. Post the links brooo

[@ENDOPRYSMyt]

Thanks appreciate the comment

[@stockey]

Same thing as mine, 3000W hub 72V battery 60 mph and 65 pounds walmart full suspension mtb, that i paid $120 used, but was also almost brand new, it's actually great because the swing arm is made of steel, i also put a larger front fork with air shocks, that are actually much lighter than the old ones, and another air shock in the back.

[@ENDOPRYSMyt]

That’s sick dude💦

[@ChrisBFerguson]

Watched it. I am looking forward to doing my own build with this motor. I bought a normal aluminum Gravity frame and fork that (that accepts 180mm rotors on them) with no other components attached to them for this. What I would do differently than you do is either have custom torque arms or Grin Tech v6 or v7 torque arms on both wheels. Also the wire for the controller facing up is a place where water can get in and damage every electrical component. I did a conversion with the cheapest Walmart bike and the worst component for that bike that would stop me from getting a heavy duty motor like this one on it is of course the brakes. Rim Brakes.

[@ENDOPRYSMyt]

Rim brakes are the worst for these things I feel you. I’m definitely going to refine this project some more and make sure everything is more water proof🤘

[@ChrisBFerguson]

@@ENDOPRYSMyt Yes that was my first conversion. Water damage because of controller up and not down. Second one. Coaster brakes and weak front rim brake led to me hitting a car going 24mph to 28mph. I would still use rim brakes for anything under 30mph though. Have 500W hub motor on cheapest walmart bike and it is just fine. Had to get rid of stock rim brakes and get tektro ones though.

[@bu56]

this video was fire man well done

[@Calthecool]

Nice build

[@ENDOPRYSMyt]

Thanks!

[@housedjnyc]

I would suggest using stronger torque arms (1 per side) as those clamps are known to break.

[@ChrisBFerguson]

I think he should use Grin Tech v7 torque arms on both sides. That frame has no threaded holes for rear racks. I have custom ones on a bike that has multiple threaded holes for rear racks.

[@housedjnyc]

@@ChrisBFerguson either the Grin Tech or fabricate some…

[@ChrisBFerguson]

@@housedjnyc Grin Tech ones use hose clamps too. I don't think hose clamps are bad but the design on the most common one which is used in this video made my current rear hub conversion wheel come off along with Grin Tech v4. Grin Tech v6 and v7 look like they will work on most bikes and they also have M16 adapters which I think the motor in this video uses.

[@housedjnyc]

@@ChrisBFerguson v7 are decent. My build will be on a 16” bike with an 8kw QS273 so I’ll have some made as I don’t want any kind of twist back there. I have a set of V7 to experiment with first but ultimately I want that motor licked into my rear swing arm.

[@ChrisBFerguson]

@@housedjnyc QS273 is definitely too much for a standard bike frame. What is in this video is the most I would put on a standard bike frame.

[@jcvideoproductions5318]

My best suggestion is to put hydraulic disc breaks on that, they are wayyyyy better for high speeds and feel wayyy better than cable breaks.

[@ENDOPRYSMyt]

[@anthonyfuentes1179]

Btw your video format kind of reminds me of vicesat. He’s a KZbinr from Spain that makes videos very similar to yours but he never shows his face. He started with ebikes and scooters and slowly went up to car modifications and other stuff like that. You should check him out. I feel like the one thing you’re missing is to expand your video “portfolio” so that you can hook a wider audience and you’ll do great

[@ENDOPRYSMyt]

That’s what I’m trying to do. Baby steps and it first starts with doing a different type of e-bike build than I normally do. Next up it will be a go cart build next month. I’ve myself all set up to starting doing something new every month-2 months. But thanks sooo much for the great comments bro I will check him out.

[@ravenrock541]

I would not want to get in a 60mph wreck on a motorcycle, let alone a bicycle. At least a motorcycle has good brakes.

[@ENDOPRYSMyt]

Upgrading the brakes and some of the components to improve stability is my first priority

[@AeyoMunch]

Anyway you can do a cheaper one… I don’t get paid by KZbin and I’m definitely broke to be spending that much cause I was an electric mtn bike

[@ChrisBFerguson]

Another question. Did you have to solder the XT90 connector on the controller for the battery? In the picture on Amazon, it looks like you would have to.

[@ENDOPRYSMyt]

It just came with the battery. It also came with a connector

[@jmhodge12755]

LaSalle seems to have gone out towards the end of the video can you please reshoot this video so we can hear what you're saying this is a really interesting project I'm wanting to put this on my trike

[@anthonyfogleman8652]

[@benchesterman1141]

I’ve built one of those but I’ve gone all out running 150a sabvoton 72v 40ah battery like how u have in ur enduro e-bike but on a mountain bike I’m not even joking goes crazy

[@benchesterman1141]

[@Stanima68]

[@ENDOPRYSMyt]

[@ChrisBFerguson]

Quick question about this conversion kit. Is it compatible with most e-bike hub motor testers?

[@ENDOPRYSMyt]

I’m not sure.

[@ChrisBFerguson]

Have you used an ebike motor tester? Useful if you want to buy the motor but need to save up before buying a battery.

[@ronbrown4551]

Hey Tommy, I have a few questions and I'm really not trying to be an ass here, but I don't understand the link that you put in the description about the motor was a 3000 watt motor, but you said it was 6,000 Watts so I don't get that. How do you arrive at that? What am I missing ? Question number two is I don't see a chain on there at least from the angles that I saw. Do you have a chain on there and if you do how fast can you pedal that before you're not pedaling anymore the motor just out runs you? (If that makes sense) I was thinking about buying a Talaria XXX with the pedal kit but apparently even with the pedal kit it doesn't give much speed to it at all with the pedals so that's why I was kind of thinking about going your route and building a bike instead. I'm not looking to pedal this thing all the way up to 50 mph but I would like to be able to pedal at least till about 30 mph. I guess question number three is I know it's been awhile but that other bike you have the Enduro how much do you think it cost to build one of those these days because the links that you have in the video for that are kind of off. Thanks

[@ENDOPRYSMyt]

So the reason the bike is 6000 watts is because although the motor is rated for 3000 watts it is being ran at 6000. This is because the power comes from the controller and battery combo and only flows through the motor. But don’t worry that 3000 watt motor could handle more like 9000 watts just fine with no issues. Also I did not add a chain to the bike for this specific video. Mostly because I was having issues with the chain I currently had not fitting. Assuming I had a chain in the bike I would only be able to pedal up to about 25mph before the gearing would be overcome by the power of the motor so it’s sort of useless. Lastly it costs about 4000 ish to build the enduro. I haven’t been making videos on it recently as much just because there is not much more to say about it for me anymore as I already have sooo many videos on it. If I want my channel to grow I need to move on and do more projects. Not to say I won’t occasionally do videos on the enduro.

[@ronbrown4551]

@@ENDOPRYSMyt thanks for getting back to me so quick. yeah I'm kind of torn whether to go with the Talaria XXX or building one

[@ENDOPRYSMyt]

@ronbrown4551 I thing it’s a pretty Evan decision. On one hand you won’t get the same speed and smooth ride that the enduro has don’t forget range. But on the other the talaria is more capable off road and will come in a neat package. One thing is for sure tho the enduro may cost 1000 dollars less.

[@ronbrown4551]

​@@ENDOPRYSMytyeah I wasn't sure if I could build a cheaper than that Talaria it's 3,150 plus tax and shipping it should be about 3,750 plus 150 for the pedal kit, and you're right it does come in a nice package and that kind of stuff. It's just that pedal thing and the fact that the thing makes a lot of noise. The plus sign it's like got a warranty that kind of thing. So I'm kind of torn between the two ideas

[@7996hobguy]

​@ronbrown4551 Build your own and don't look back. Upgrading and modifying will be easier, as well as being able to select your own components and putting more into the areas that you feel are needed. You will also save money, and learn a lot along the way.

[@jashuasmith9361]

Between the qs205 motor and the qs273 motor, which one you more prefer?

[@ENDOPRYSMyt]

Qs205 the 273 is tooo heavy.

[@jashuasmith9361]

@@ENDOPRYSMyt I have the qs273 and was always considering the qs205. I thought that the QS 273 would be more robust for hot days and steep climbs in not overheating. And efficient when it comes to utilizing energy and not having it lost through over heating. But I see allot of videos with qs205 handling allot of power. I always thought that if you put too much power in a motor, then the power of the motor is lost through heat. And even if you cool it with stator aid and hub heat sinks, it is still lost power. Not that Im against ferro fluid and hub sinks, that I think it should be used in the power rang of the qs205 regardless, because you’re going to have hot days, potential steep climbs and Times, you are running it at its peak for a good while. I think a decent range for the qs 205 is between 6kw to 10kw. I always thought a good range for the qa205 is around 10kw. I always here that the qs273 needs more power to operate because of the weight. Dont know how much of that is true. I want to put a bike rim on the qs205 and considering a 18get 70a 90v infineon controller. I already have a 150a 120v yyk controller. Dont want too much bulk. And nice build.
