Electric BSR

[STOOLRIDER]

Hello,
New to BSR buidling, I am looking to build a Electric BSR mainly to cruise around the subdivision and drink beer, I need some advise/input on Electric motors/speed controllers/battery combinations, I am looking to build an Electric BSR with a top speed somewhere between 20-25 mph, one that has an extended run time, (not a car starter with short run time), One that will run for several hours without recharging. I have been researching a few motor kits on monsterscooterparts.com , I was looking at a 36v 1000 watt motor with speed controller and throttle kit, will this give me what im looking for speed wise? Run duration? With this combo will it lurch out from under me from a dead start, Do I need to worry about drive shaft stability with this motor or Would a gear reduced motor be better, I have also considered a 36v 600 watt gear reduced motor would this be any better,

Any help will be really appreciated

Thanks

Hey StoolRider, I made my BSR with the 36V 1000 watt motor kit from Monsterscooter. It performs very well. I did not know what to expect, but when I got it running it was awesome. It has plenty of torque and the battery life is excellent. The best thing is all you here is the chain noise. I will post more pics when I get mine back from the powder coater. Good Luck

[STOOLRIDER]

Hey Lanman,
Thanks for the info on the motor, Did you build your BSR from the Classic Plans available here? What size Sprocket and chain are you using on the rear axle? How fast is yours?.


Definately post some pics if you can..


Thanks Jeff

[Lanman70]

I made mine mine like the ProStreet with my own touchs added in. Before I tore it down for powder coating I had #35 chain and 74Tooth sprocket. I am going to try a 64Tooth sprocket when I reassemble. It had plenty power to climb up my yard through the grass. The batteries fit neatly in a row and you can see the controller in one of the pics. I have changed the mounting since these pics and I will post them later. I purchased most all cart parts from minichoppersocal.com and all the electricals from monsterscooter.com.

Here are a few more pics of my build, more to come.

I had to drop my electric stool build, and switched to gasoline motive power. But, I still have the controller and the motor, along with a 24 volt charger. As soon as I figure out how to wire the controller, I will start again. Tonight, I add gas to the engine and take my first ride.



I guess I should replace my avatar picture.

Hey Lanman,
I decided to build 2, So Ive been cutting and welding on and off for the past couple weeks, You mentioned your battery life was pretty good, Is that a couple hours of continuous use , more/ less? , What battery charger are you using and how long to charge all three batteries, sorry for all the questions, just never really dealt with battery powered vehicle before....

Thanks Jeff

[Lanman70]

This is my first experience with electric motors/batteries too. I am using the 36V 1000 watt motor package from monsterscooter.com. I can tell you that my BSR ran all afternoon with a bunch of different riders and still had plenty of battery left. A lot of the rides were around the yard a couple of times and then someone else would jump on it. At the end of the day I plug it in and it is ready to go in the morning. I am using the XLR 2 amp , 36V charger and charger port. The Batteries are Item # X99-0704 and fit nicely under the Bar Stool. Everything was very easy to hook up, and it runs smooth and quiet. You can see in the pics that used a different terminal block for the wiring, that is because we had the parts and pieces at work. Send some more questions! I will be glad to help. I should have completed pics of mine later this week.

I have been thinking about building something electric, I went to the site you mentioned monsterscooter.com but all I get is a redirect. Am I missing something?

Hey Lanman,
The plans for this BSR call for a 40" axle but they have you cut it down to 29" , Is there a reason? Im asking because I want to order a complete axle kit for these but can only find them with 30" or 32" axles, From Barstool racer supply, will these kits work, what did you do?

Thanks Jeff

[Frank McGrath]

I bought the 32 in axle and find it was too long and will cut it down to length I need.

Hi !
My name is Per Jenssen, and i am living in Norway, Europe.
I have already built a gas stool, but i got curious about electric...

One thing i noticed after scrolling the pages at the parts supplier was that the motors typical had 3000 rpm. I did some simple math with the sprockets available, and found that to get to about 20 mph with kart tires, you would need a different set of sprockets. More like 30 theets rear and 20 theets front.
This is the same probem i had with my gas stool, i had problems finding a suitable rear sprocket with the correct number of theets.

So, are there any other supplier of sprockets, do you spin the motors more, or do you just accepts lower speed ?

[Lanman70]

I just got mine reassembled after powder coating. I used a 10 tooth sprocket on the motor and a 64 tooth sprocket on the rear. I clocked it yesterday at just over 22mph. I am using the 36V 1000 watt motor from monsterscooterparts.com. I tried an 18 tooth sprocket on the motor and it was faster but lost too much torque. I prefer the low-end torque rather than top speed. I am very satisfied with this configuration, all you hear is chain noise. Good Luck!

I order all my stuff from BMIKARTS.com much cheaper than barstoolracersupply.com and their combined shipping is AWESOME!!!

[Lanman70]

I used the 1" x 30" complete axle kit from minichoppersocal.com. This was my first BSR and I was not sure what to expect either. I bought all my parts from the same place and it all went together without any modifications. The axle in the pics is 30" long. The hubs can be moved on the axle for wider or narrower. You won't have any problems. It is all much easier when you get the parts in your hands.

Can you link the motor, ESC, combo you used from monsterscooter

Thanks

Lanman,

Awesome job on the BSR! I have been reading your posts and have a few questions that I have been unable to locate answers for about your BSR now that you have had some time to become familiar with its characteristics.

1.) a good guess on runtime (or mileage) from fully charged to completely dead? I understand there are quite a few "x factors" in that question, just an average idea running the machine under average conditions.

2.) can the 36volt 1000watt motor pull wheelies on your unit? If yes, I see you were contemplating dropping to a 64T rear sprocket. Did you? If yes, does it still pull wheelies when you changed to that gearing?

3.) what type of top speeds do you feel you achieve under the two different gear ratios you mentioned?

4.) Any idea on how much your machine weighs?

Thanks for your info. I am new to the sight but have been contemplating building a BSR for years now. I really like the idea of the electric version and am thrilled to find someone who has built one! Especially one that looks as good as yours. Nice job!

[Lanman70]

Thank you. The runtime is tough to figure. All I can tell you is it performs great around the neighborhood. Driving it through grass and up hills drains it quicker, but it still last long enough for the kids to get bored. My BSR will not pull wheelies. With the 74 tooth sprocket it will just lift the front enough to get a little air under the front tires. I have the 64 tooth sprocket on now. Although it runs some faster, I prefer the 74 tooth. I like the torque and power especially as the batteries start to fade. I have not sped through any radar traps, but I am sure it will do 20MPH and for cruising the neighborhood it is plenty fast. I am not sure on the weight. I used 1/8 wall tubing for the frame. The batteries and motor are 35 pounds. My guess is 80-90 pounds. I will post pics of the Parade this weekend! Happy and safe 4th everyone!

[getinzone]

Lanman,

Could you describe the wiring that you did for this BSR or maybe a diagram? What else of anything did you need besides Motor, Throttle, Controller and Batteries for electrical? So your final setup you like the best was the 10 tooth motor sprocket and the 74 tooth axle sprocket for #35 chain? Where did you buy the sprockets and what size shaft for motor? You had your motor and brakes reversed early and switched, was that just an error you made and found the motor rotation was opposite, or did your change the rotation of the motor for other reasons?

Thanks,
Your BSR is graet!
Kurt

[Lanman70]

Thanks Kurt. I like the 74 tooth sprocket for the extra torque. It goes fast enough to cruise the neighborhood. I bought the 10 tooth sprocket from McMaster-Carr and then bored out the center to fit. I do not remember why I switched the motor to the otherside. The motor will run either way just by switching the wiring. I have forward and reverse just by flipping a switch. I will try and get a wiring diagram together and see if I can post it.

[Lanman70]

My son will run it for a half hour non stop and it still has power left. It will cruise plenty fast enough for the neighborhood streets. I do not have the speed differences between the sprockets, but I will take slightly slower and more torque with the 74 tooth. Mine will not pull wheelies, but it will jump enough to scare people when it takes off.

Thanks Lanman, I would love to see a wire diagram if you make one up. I received my stool from UPS today so I will be starting on mine soon.

The first barstool Ive ever seen was about 25 years ago, I worked summer time for a Hamms/Oly distributer loading trucks and they had one there. On the front and rear scoop had a Hamms logo, and the driver would wear the Hamms Bear suit while driving it in a parade. It was electric also, but had 2 starters for the power, one each on rear wheels. Had one push button for each motor fixed to the steering wheel. You had to feather back and forth to get going. This thing was scary fast and hard to control.

That why I chose going more your route, a little safer and nicer looking.

On a side note, I seen a pic with a vette in the back. What year is that? I was guessing 70-71 as I cant see the front bumper. I had a 69 and my side vents are different. Also know its not a 68, it had different door handles. Any how, nice looking car and thanks for the help!

[getinzone]

Here some pics of my old 69

[Lanman70]

It is a 1970. All numbers matching and correct. 350/350 4 speed. It has power steering, am/fm radio and Hard top, that is all the options. The non power brakes make stopping quick exciting. I have not driven mine this year, putting to many miles on the Barstool. Do you drive yours much?

[mikel]

I do not have the speed differences between the sprockets, but I will take slightly slower and more torque with the 74 tooth.

I started building a bsr, am liking the idea of electric motor more and more. 36v/1000watt setup sounds very resonable for my budget. but i want to be able to wheelie. is there an easy fix for this with an electric setup.:bigcry:

Did not drive mine for a year or so, ended up selling it and bought a motorhome. This is on of the reason Im building an electric BSR, so I cruise around the RV parks without alot of noise.

Started my frame. Had all metal work done and delivered to me for $61. It's nice having a buddy that works at a steel mill. Have the barstool, front spindles kit, rear axle kit and axle. I accidentally ordered a 1 1/4" bearing kit and mounted the hangers. I now have to remove and install the hangers for 1" bearings. You would think the OD of the bearings would be the same and just change the ID of the bearing. Oh well. I also have the motor kit on it's way. Will post some pics along the way.

[mikel]

Which motor kit did you buy? and from where? i've been looking for a kit that is bigger than a 1000watts but don't want to go over board, maybe 2500watts?

[getinzone]

I bought the 1000w one posted on this thread. That was the largest one I seen from monster scooter parts.

[Lanman70]

The 1000W motor will work great. I pulled off the sprocket and put one on for #35 chain. Did you get the controller with it?

[getinzone]

Yes, bought the kit with controller, throttle and motor. Im waiting for motor to arrive to get shaft size, I will then also go with a 10t #35 on motor. I went with a 72t #35 for axle. That is what I found for a cheaper price sprocket instead of using the 74t like you. Don't think it will change to much, but will try it. Not that saving $10 on the sprocket is much compared to price of wheels and tires :)

[Lanman70]

I bored my sprocket and then used a screw on the flat of the shaft. Maybe you can see in the pic. If you need a better pic let me know.
Good Luck

[getinzone]

Here is the start of mine. Parts are coming in slower then wanted, but did not order everything at one time.

Looking good, keep the pics coming!

Lanman,

I need your help with some electrical. Ok, so have my batteries connected in serial, + to -, + to -, take the lead from battery 1 neg and take lead from battery 3 pos. Measured volt for 36 volts.... good! My question is with the motor kit, the +/- from battery goes to black - and red + of controller wires. The black and red wires from motor go to blue/yellow wires of controller but dont think it matters what way I hook up, it should turn motor either forward or reverse? What about the throttle wires, how did you wire them? The throttle comes with Black, Blue and Yellow and connect to the controller that has Black, Blue and Red. I think I fried my controller board and would not like to do that to many times. So if you could, can you look at stool and help me out with the electrical. I have the same batteries, controller, motor and throttle as you. Thanks

[getinzone]

Alrighty, figured out the wiring. I did smoke up my controller but was lucky just to fry a tracing on the circuit board and not any of the components and was able to fix. I forgot this controller was wired for an on/off switch and has to be wired, after that I got everything to work.

[Lanman70]

I also shorted out a controller. I got excited to see it run and did a poor job wiring. Once I took the time to do it right, it all worked great. Can't wait to see some pics. Good Luck.

I forgot this controller was wired for an on/off switch and has to be wired, after that I got everything to work. please post the correct wiring.....i'm planin on runin the same set up..... thank's walt:blue_blob:

[getinzone]

Walt,

Im at work right now so I'm doing this off the top of my head.

3 Batteries
b1 b2 b3
- + - + - +

Jumper wire from b1+ to b2-, jumper wire from b2+ to b3-
Wire from b3+ to red 10 gauge (thick) on controller
Wire from b1- to black 10 gauge (thick) on controller

Now depending on what side you put the motor on will determine what way to wire motor to controller. Either way will work and not hurt anything, so connect black from motor to either blue 10 gauge (thick) or yellow 10 gauge (thick) and red wire to the one you did not connect the black to.

I bought a keyed switch to use on mine, or you could use a toggle switch or I would think you could connect the two wires together from the power lock on the controller (red and blue thin wires) to bypass a switch. You must either use a switch or connect these wires together or you will have no power to any other connectors.

Throttle
Hand throttle connector, 3-wire. Plug your 3-wire hand throttle wires into the three prongs on this connector. Black to Black, Red to Red, Blue to the third wire on your hand throttle (Blue or Green or other, mine was yellow).

That is as far as I have got so far. I purchaed a hand brake with a switch to have a brake light. That should be easy to hook up though. I will post more as I get further along. Just have to mount brake calipers and hook that up and should be rolling after that. I also need to make some new tie rods, the ones I received had right hand threads on both sides?

were could i buy my husband a electric barstool racer, a complete ready to go racer, he wants one but has zero time to build one, he would like it fast with racing slicks painted black can anyone show me the way to buy one looked all over and can't find a web site that sells them:cool_dude:

[mikel]

started building last year, just finished cutting to size all the 1" square parts for my bar stool. cut on band saw then cleaned up the edges on the mill. ready to start tack welding soon. at this pace ill be done in another two years. actual time is a few evenings in the garage. plan on making it an electric barstool racer. thanks all, i enjoy reading all your posts, keeps me motivated, i know ill finish it, just going to take some time. If there is anyone in the area working on one, i'm in whitby, ontario.
