Electric Bike 4.0 - First Test ride

[@TomStantonEngineering]

I've just realised it may seem like I wasn't wearing a helmet, but it turns out the GoPro is mounted to the helmet and therefore I had to briefly remove it to check the GoPro battery! Thanks

[@DarkMineLP]

Do a burnout!! :D

[@brantwedel]

Do a barrel roll!!

[@forfengeligfaen]

Mehh You should get a safety tie like Colin Furze.

[@TomMarsh1010]

I know people get bent out of shape about helmets, but bike helmets are generally rated for falling of a stationary bike, or maybe walking pace. They offer little in the way of protection at 45kph, especially vs a tree. You might want to look at using a helmet designed for a motorbike... or just not wearing one and enjoy the wind in your hair.

Think that is the best ebike build I ever seen. Clean, cool and clever!

[@TomStantonEngineering]

Thanks!!

[@johnsweda2999]

Yes I must agree I want one I prefer the other model looks a bit more sexy

[@letmelogin2903]

Its a hub motor, discrete and almost silent

[@flvffette]

@@letmelogin2903 did anyone ask??

[@rustjupiter]

Tom I have to say that your ebike videos have helped me more than any other set of ebike videos. You're version is closest to what I want to build and your insight and tips are outrageously helpful. Cheers to you mate.

[@troychampion]

Tom Stanton Tomorrow will make a year that you've had the final version (at least according to your video blog) of your E-bike. How has it held up? What would you do differently? How often do you use it anymore? I have a regular bike with multiple gears that I ride a few times a week, I am considering building an E-bike for myself one day... are there any tips you would add to your Vlog having gained all this experience to a novice maker.

[@Gribbo9999]

Thanks for km/h Tom. I know it was as mistake but much more comprehensible for most of us cyclists (global perspective). Keep it that way! That's a real machine well done!

[@redsquirrelftw]

Yes Metric all the way, should keep it that way. Only yankies do MPH. :P

[@CNile-se9xw]

I have to say, I'm extremely impressed, you've articulated your adventure beautifully. I really appreciate how you're open to disclosing problems & your thought processes to fix them. All the very best to you (from Australia) young man, you're a champion. 👍

[@seavee2000]

Brilliant. I want one.With only one leg that works I can see the benefits of an e-bike....especially one as well engineered and thought out as this.

[@mhannan6328]

Outstanding engineering and development. Humble presentation of a great work. Thank you.

[@mysterOrel7924]

dude u deserve to have your own electric bike company !!! this is a great job love you Tom !! from Sénégal !

[@calebsherman886]

Atleast like sell it as a kit or something.

[@mysterOrel7924]

yeah sure !! something like that would be awesome !!

[@joetke]

I was waiting for this demo. An achievement indeed. The speed is pretty high. Your design is above the average Tom. Thanks for sharing it.

[@squidlings]

Foooooookin hell! That is amazing. I built a 1000w hub fastest I've had is 56kph going down hill and it felt like 100kph. This is next level. Love it! Your acceleration is scary

[@sethcohen3938]

Could you link to a parts list for the motor, VESC, etc. it would be very helpful.

[@akihitolucilius2881]

Hey Tom, I can't recall if you ever mentioned much about those batteries in any of your videos? I'm considering building something similar to this myself, and I am very interested in how you wired up those batteries and how you balance all the cells! What charger do you use?

[@miguelcontreras5782]

Isn’t 800 watts for sustaining 18-20 kph a bit too inefficient????

[@Tomas-ml9nv]

Pro cyclists average 40km/h on 400 watts in normal conditions

[@jbalatutube]

I get about 220w at around 30km/hr on my ebike. Maybe your watt readings aren’t calibrated ?

[@juhopeltola2561]

My bike dont need that much either. Under 200w @ 20kmh and goes 40kmh whit 36v and 15amp current limit.

[@bradleyland]

It depends heavily on conditions. We don't know how soft the trail is or if there is a gradient. He noted in the video that the gradient is GPS based... which is just about worthless.

[@JaBooBaLoo]

It's mph. Not kph. He left a note at the beginning say he doesn't know why it's displaying kph. He set it to mph.

[@philipps3ddruck]

Hey, is it possible to use that data overlay .fit file with final cut? Thanks :)

[@juhopeltola2561]

My bike is is chain driven. It has take lot of work to get chain line straight, but now it works. I have brushed motor and good torq, easily wheeling in 18th gear.

[@dyrectory_com]

When are you selling kits for this eMotor ? ⚡️ 🚲

[@WilliamDaviesDev]

Never

[@aerossignol]

Truly epic and inspiring video. you've come a long way since the original V1.

[@locouk]

What happens if god forbid, you have to pedal it? Can you disengage the drive system so you don’t have to pedal against the motor and belt friction?

[@letsgocamping88]

Green Silver with motor braking or regen turned off then there will be only a tiny amount of resistance. You’d probably notice the weight of all those batteries more

[@Matt151022]

Love your videos man! It has evolved so much over the versions!

[@pancho97100]

So many features similar to the first Harleys. Aweosome build

[@austiwawa]

Awesome job Tom! That looks like a quality speed controller you chose as well.

[@TomStantonEngineering]

Thanks man! Really enjoy your drift trike vids!

[@sheldoncyril6194]

best diy ebike i've seen so far...wouldn't mind building one exactly like yours

[@xxtrengt8871]

This version of the ebike is really great, it made me start an electric minibike build ;)

That engine just peaked at 5 horsepower, quite impressive.

[@anthonymedford5380]

Great job, you should add a USB port to the battery pack so you can charge your Go-pro when it gets low.

[@fahed7316]

Yeas

[@MelkiSilvas]

yeeeeaaahh! So much powerrrrrrr!!!!! nice job guy!

[@ldmcnutt]

Dude, this is sick! This is your best project yet!

[@dewexdewex]

Looks very good indeed. I would be inclined to cover the primary and secondary drives near the motor for when winter comes and you ride with trousers. You wouldn't want them dragged into the pinches between the belt and any pulleys.

[@GrandadIsAnOldMan]

Great video, I am not into bikes, not even electric bikes but I do enjoy your technology and the detail of the information you put into your projects so an excellent video to watch for the information you have provided and visually a great day out anyway 😊😊😊😊

[@headybrew]

Wow, I wish I had such beautiful places to ride as you do.

[@umbra1016]

Absolutely wonderful presentation! Great job!

[@Dave64track]

Wow great job now that's an electric bike just take it easy in the woods at that speed especially with tree roots etc. Love to see a test run on a quiet road good job enjoying the videos keep up the good work.

[@RamyRC]

amazing!

[@revgro]

At time 10:19, you discussed the effect of the motor mount on the motor (Lenz's Law). Do you think there is a Lenz Law effect on your CNC Router Spindle due to the aluminum spindle mount?

[@Matt151022]

I love seeing the progression of these. Also your motor design is so awesome. I love it. Id like to do something similar for my project.

[@USWaterRockets]

Please test it out on a paved flat road so I can compare your top speed to my personal human powered best! It looks like a lot of fun. Also, can you give an estimated range for the batteries? Can you also charge the batteries by pedaling the bike with the wheel off the ground?

[@Stevo_1998]

In the video he did say that the batteries will do about 15-20 miles (24-32 km) Also, in one of the earlier videos he reckoned it'd do 30-35 mph (about 48-56 km/h) on a decent bit of path, and in the video (going up hill) he pulled 45 km/h (28 mph), so if you can manage that, Tom's E-Bike has got some serious competition (lol)

[@MeriaDuck]

And that was even bloody uphill at an approximate 9% incline... I've seen model aircraft with less power (approx 3.7kW) lifting up themselves *and* a 7m wide 1:3 scale glider. 4kW is a s*load on a bike!

[@Surestick88]

He could Strava his rides and grab a few KOMs with that bike.

[@iamthejohn7064]

That rear pulley is very clever, never would have thought 3d printed plastic would handle that application

[@danhenton1978]

Great to see this bike up and running. I use the same Vesc6 Tampa on my 12s4p dual direct drive mountain board. You could totally cool the motor by adding some vents in the housing and then use a kitchen splash screen mesh wrapped and then glued between interior walls to protect against dirt and other objects from entering. I have done a similar thing for my Trampa motors. The print walls end up looking printing like this: | wall | mesh | wall |. I've found that the spinning motor itself is able to produce enough airflow to actively cool itself. Also its great you are going to 3dprint a cover for the Vesc but Tampa also provides a rubber cover which would also do the trick. looking forward to seeing more progress!

[@AverageJoe8686]

You could totally replace the 20:40 tooth with a BMX freewheel and derailleur idler so you can go fast down hills.

[@jessemoody2218]

Wow, that looks like a blast to ride! This has me seriously considering building one too! Great job Tom!

[@silasmarner7586]

Fabulous result!

[@musicauthority7828]

It has pretty similar performance to a Sur-Ron. the Sur-Ron has a longer range interesting. the Sur-Ron has forks and rear suspension similar to motorcycle. same with the wheels and tires. the Sur-Ron also has regenerative braking.

[@solarfunction1847]

Hey Tom, really great video to the series of updates on version 4.0. I spent all day today getting cheap prices on all the parts to do this myself using my Carbon Fibre 26" Mountain Bike, a 12s 8p battery 50.4v 20 Ah & I found a 44V 48V 50.4V 12S 150A Continuous BMS / Balancer. The build is quite expensive. I was wondering, the motor drive pulley 20T & motor driven pulley 40T did you go with HTD 5M 15/20/25mm Width & the 20T to 180T wheel pulley did you go with HTD 5M 15mm pulley's & belts? They are 5mm pitch 20T 8mm bore pulleys & I'm guessing you used 5mm pitch 20T & 40T 10mm bore pulleys because I've not found a 5mm pitch 40T 8mm bore pulley yet. Tom, I don't have access to a 3D printer to make the 180 Teeth 5mm pitch 16mm internal diameter wide plastic wheel pulley that mounts onto the back wheel. Is there any way we could work something out where you print up a pulley & I can pay you for materials & shipping using Western Union? I can make up all the aluminium brackets & frames to put it on, I just need the pulley with it's holes ready for tapping M5 so you would only need to locate the holes with a 3mm drill & I can sort the proper tapping drill size & threads. Thanks. Mark, Perth, Western Australia

[@siriosstar4789]

Very cool. Brilliant!

[@RoboticusMusic]

I noticed that the elevation telemetry isn't accounting for acceleration/deceleration. Is there is a meter that is really good at not having that problem during acceleration and braking on steep bumpy inclines?

[@AirCommandRockets]

Very nice work Tom. I was half expecting you to overtake a couple of storm troopers on their speeders on this forest moon of Endor. :)

[@TomStantonEngineering]

Thanks George!! Looking forward to seeing your new 2-stage rocket launch!

[@AirCommandRockets]

Cheers Tom. The rocket is still some months away from launch. Love your channel by the way, you have some very nice projects. Keep up the great work!

[@ivonakis]

sound is awesome

[@AdmiralThumbs]

To prevent overheating of the motor, you should cut out ventilation holes on the motor guard (or design a new version with holes).

[@Tletna]

Maybe an easily cleanable mess cap of some sort???

[@chevsev]

lenz law is a formula to figure out induced current, its eddy currents that act on the motor to counter it spinning.

[@jamespfp]

2:00 -- WOW Tom, the overlays for speed and RPM? Totally awesome.

[@adamjohnson6779]

very slick build well done tom

[@AlexBESBiKer]

Surprisingly your E bike looks very neat and tidy than other DIYs And I always think that hub motor doesn't do the best job! Well done! Tom!

[@mcaddc]

Great work! One of my favorite ebike builds!

[@Jskdog]

Excellent build, very impressed. How feasible would it be to have a display with real time data mounted on the handlebars?power/speed/voltage/remaining distance etc?

[@Uap-i3o]

How much would it cost to make this I haven't got the technical know how on how to take something like this but if you ever go into manufacturing a kit like this I would buy it if it wasn't to expensive it looks a lot better than other kits I've seen.

[@jimhofoss9982]

great engineering! what’s the weight of your bike?

[@PetesShredder]

Have you got any info on the batteries you made? Looks like 18650 cells packaged together... Would be interesting to see more on that, and how you charge them and and what kind of charge speeds you can run at? Thanks

[@stumpy1495]

You should lift the motor further away from the frame to stop the currents being induced their too.

[@cllris]

How does it ride tradtionally with the pedals now? Or is it more of a pure electric bike rather than moped style? Is there a lot of resistance. If so do you have a plan to be able to switch etc?

[@chris2944]

Once you get to a certain speed the pedals don't do much. For me on mine (1500w hub motor) the pedals don't really help past 40km/h

[@cllris]

@@chris2944 i get that 😂 its more whether its rideable without the motor. Eg if it runs flat and your still a couple miles from home.

[@chris2944]

Oh yeah you can pedal but if there's a hill you're fucked unless you're Chris froom.

[@SomethingTheBestEver]

Cool! Didn't you think about installing overrunning clutch on the main driving shaft to ease the free riding?

[@jimmarshallman6300]

Downhills were invented to go FAST! >8^) I'm enjoying your channel .... The bike stuff in particular ..... 👍👍

[@Woolypopopeepee]

You should add regenerative breaking to change the batteries mid ride!

[@tigeroats913]

I would honestly buy that

[@biggusdiggus3337]

Do you sell the kits if so how much. Or where did you buy the motor. Brilliant videos as always. Thank you.

[@evanpalms4571]

Do you have blueprints for this design? As in the specific gear used for this modification. Thanks.

[@ΠάνΤρίμης]

Excellent video and work Tom! You're an inspiration mate! I an designing my own ebike and your information is so valuable! Thank you so much for sharing Sir!

[@Mr-nt8mz]

Cant find words right now, but one thing for sure, you're awesome ! I am looking for ways to also do it Id love to have this setup. Way more convenient than getting a heavy wheel with motor.

[@tonysshadow]

Ild be curious how durable 3D printed fenders would be for your bike. How thin they could be, what kind of design would be necessary for any shortcominings.

[@1Guy12]

Have you thought to use two spider gear vertical, one mounted on the motor and one one the back wheel? I'm a physicist not an engineer, but engineering is a very tempting field of science, so it's just an idea and I would appreciate if you answer...Thanx in advance and your idea for the E bike is the best I've seen till now!

[@ОлегНаумыч]

Парень молодец! Так держать!!!

[@gaivoron]

Can you make a kit for sale?? I would love to have this fitted to my bike!!!!

[@TheNerd484]

Noyce! Have you considered designing a motor cover with vents for cooling?

[@redkingwell4047]

Wicked design! Is there a way you could make it have re-gen breaking ? So when going down hill you could recharge :) ⚡️👍

[@sabelch]

What if a loose pant leg or sock got caught in those gears? Seems like for safety the motor housing could be extended to cover the other moving parts.

[@nathanwest2304]

what did all the parts cost in the end? I'd be curious making this in a weaker version since anything above 30km/h needs to be registred as a moped and that is an entirely different beast to tackle in my country.

[@reggie3h694]

You could design a motor housing with holes and a space to put a screen and small filter to increase cooling.

[@redsquirrelftw]

Could maybe even put the holes at an angle to match the rotation direction of the motor, the drag might act a bit like a tesla turbine and suck air in. Then have a way for it to exit.

[@Richard-Freeman]

Wow! A real life application of Lenz's Law.

[@lasersbee]

Seems like you figured all the Electrical/Mechanical glitches out. Well done. Seem to ride well. Would have liked to see the top speed and wattage on a level/smooth asphalt or cement non dirt or gravel road.

[@tjohnson4062]

I'd love to see some numbers on up, torque, bike and rider weight, so some calculations of pulling different grades. At what grade incline does the motor begin to heat up?

[@felixschalck1748]

Hello, very interesting stuff - thanks for sharing. what belt width did you use ? Looks like 15mm, be that seems very narrow for 2-3KW ?

[@ForTsz]

Its hartd too imagine this project really came outr thisd great! Have good fun to ride it and you can get your self a basic bike computer which can come very cheap and also gives you real time accuate speed too.

[@Nidls98]

The final upgrade would be a charge circuit when going downhill so it would increase the range of the bike a bit i think

[@wackyack3165]

Very impressive - well done.

[@power-max]

Why not a hub motor? It would probably not be quite as torquey but would be much quieter since there is nothing spinning at audio frequencies

[@locktite323]

You mentioned about having a temperature sensor inside the motor casing; would it be feasible to have some sort of fan with a filtered intake to help keep the motor cool?

[@gaivoron]

Have you thought about making a CVT "transmission" for your bike?

[@SimOn-bz4xy]

This is so cool, amazing build! What type of belt are you using, and what type of gears? Im planing of building something like this, but im thinking of a bigger gear on the rear wheel and direct drive it on the motor, or do you think this will cause to much stress on a motor? Any one got tips for good motors ?

[@universal8264]

Tip: Pay attention to gear ratios, they are important.

[@k.sheppard4943]

Well my English isn’t that good that’s why I’m asking this with basic words does plastic band melts or gets thicker because with that amount of power it should broke the pulley and melt down itself isn’t it what type of plastic did you use on that pulley? It’s incredible and how can that band hold on

[@Remarkable0]

How long go in a single charge? Which watt motor you used??

[@Julian_Bester]

You should add a fetacher that you can charge the batterys when you go down hill or when you pedal

[@cffellows]

I'm sure you've mentioned this before, but what are the specs on the motor? KV? Frame Size? Max Amps?

[@GoodEnoughVenson_sigueacristo]

Hi, what would be the best way to make that motor quieter? I have a 250w hub motor, and it is quite a bit quieter than that, and when you go on to the much larger hub motors, the noise can go down quite a bit depending on how hard they are being run. Is it just the type of motor, or is there some way to make it quieter?

[@Andithemago]

Hi from a fellow engineer from Spain What is the configuration of the battery? (Like 5s2p and so) Great proyect, for sure the cleanest here; and also well explained. Thanks in advance

[@TomStantonEngineering]

It's a 12s5p battery. So 44.4v 15ah. Thanks!
