Power Up Your DYU D1/ Jetson Bolt E-Bike - Battery, Controller Upgrade & More - Holmes Hobbies 

Problem with these videos on RU-vid they hate to show or link u the site for the controller.....

I spent the last 5 months making a parts list. The last couple of things get here over the next 2 weeks. I am running a switch so the 6 aH will be an emergency tank, and a 14 aH will be the main. I have replaced the entire steering assembly including the headset; 20 inch suspension forks are the business. BMX bars, 9 inch rise. 46 tooth crank with 170mm arms and extra thin peddles. The 6 aH battery fits in a "scooter bar bag" if you cut out the purse like bits first. The whole thing weights about 12 pounds less than stock.

So much easier to install a 750w, 48v Bafang Mid Motor (BBS02B) than trying to install an upgraded controller, IMO - I just did that on my Jetson Bolt Pro coupled with a 52v 'shark battery' (installed on a rear rack) and I'm getting 19-22 mph out of this pocket rocket and one can keep the stock motor set up as a backup alternative. Yep, it's bit costly ($600) but it came with all the wiring, a selection of digital displays, programable controller, hand brake cut offs, head light set up, internal PAS (5/6/7/9 levels) and can be programed for high torque (wheelies) or smooth take offs via app. I've tried about 3-4 other set ups using Ebay, KT & EBW controllers w/HIGO connectors, etc. (for neatness) that just didn't work with stock motor, so mid-motor was the answer and it's great. I'm currently installing a 52-toothed chain ring to get a bit more mph out it, I estimate about 3-4 mph faster with this set up and it only cost $22 bucks + chain links.

I would pick up a diy kit for the jetson bolt from you. I was given a bolt to help get me around town due to no vehicle. But original owner says a wire fried from charging port to battery. But I weigh a good 245# and a longer run time would be needed.

I'm currently upgrading my stock controller to a 48v brainpower controller + 48v 16ah battery. I'm also including an lcd s866

I wish you were my neighbor! With all of your interests, you would be a great guy to pal around with! Keep it up, love it!

all of Holmes Hobbies moves are heading into the right direction! as for me these mini E BIKES got me very interested first i seen them,my god imagine the revolver series E BIKE

Curious why you wouldn't just install a high current DC switch into the battery cable? Simple as wiring up an adaptor cable between the battery and controller through a switch mounted in an accessible location on the frame/cover/wherever, then there's no mucking around with plugging and unplugging. Make it a 2 pole switch, add an LED in series and the battery is completely isolated and you have a visual indicator that the battery is disconnected :)

I just fininshed mine 28a controller 48v 20ah 30a battery with a M5 display. 22,23mph.

This is awesome I would totally pay you if u did this modification for my Jetson bolt pro

I have so many electric scooters. They are a blast.

There r plenty of vids on Bolt mods. I have a Jetson J5. Can u please make a vid on upgrading a J5

Just bought one on market place for 100 with bad battery. This looks fun

HUGE value for the cost

2 wheels helps to keep you fit also.. if you have pedals :). Love this upgrade vid series, Thanks

You don’t wanna take advice for me I do not know anything about electricity. I learned from watching you.

How to change the battery cable from accelerator connect??

About ready to fire up a Crawlmaster Expert we purchased from you.... This will be our first Holmes Hobbies product 👊😎 Also thanks for the quick response via customer service and VERY fast shipping 😁👌 will certainly be ordering again!!!!

How do you connect the battery and controller to motor

Like a scooter there may be a loop in the controller if you cut it should get you more speed as well but always check it out and see b4 you cut anything please 🤝🏼🫡

Dude you are Awesomely I just bought a Leadzm Smart Electric Bike D1F (no pedals = scooter). Same bike. Different name.

looking to upgrade range

My Jetson bolt pro goes 22mph (I'm 215lbs).

I need one of your modded controllers for my build. It's a jr hardtail fat tire bike. I'm running a 1500W, 48V rear hub motor along with a 48V 20 AH battery. It's rolling 20" wheels. I don't use pedal assist or safety brakes. I live in Vancouver B.C. thanks bro. Klay

Can someone explain to me what is the role of each part: battery, controller, motor? Thank you

Next thing imo u should do is get rid of the T-bar and use ape hangers with a BMX neck it'll look a whole lot better

Is the controller you mentioned in your video still available to purchase

Hey you are prolly one of the best people to ask, how do you charge and store your ebike lithium packs? do i need a lipo bag? are they safe? thanks and rock on!

Do you have the link for the battery, please? Also, a series of upgrades for chick bolt owners would be cool. I have rudimentary mechanical skills, but would like to upgrade my Jetson!....kek!

How much is the battery, because my own jetson battery don't last again

hey buddy, I need help with my scooter, has power,but the throttle won't work, the scooter won't go, please help me!

This is great! I have a challenge and I’d like to know what you think… I have a working e-bike with a very basic controller, everything works, however I am stuck with the out-of-the factory speed. This bike doesnt even allow me to reach 25Km/h considering my weight. All I wanted to do was to have a lil more speed, nothing crazy. So I bought a KT controller and display thinking that I could change the speed limit. The new controller is supposed to be better than the original, better mosfets etc.. However it doesn’t work. The display turns on the bike, I can even browse thru the parameters but it shows 0 battery charge, hence nothing works. I tried all sort of things, like swapping the hall sensor cables to see if there was some mismatch but still nothing. Clearly there is current from the controller cause I measured 3.68V at the Throttle cable when the controller was plugged to the motor and battery. Battery is 48V 15AH I dont think is the problem, the display turns on, it just doesnt comunicate with the motor (250W) My naive question: How can I proceed with modifying the new controller and make it “like” the original? I thought about making a new one from scratch but it might be too difficult for me, Besides I’d still have the display problem, I need one to turn on the bike, speed regulation, headlights etc.. I suspect it might be something “simple”, related only to the power circuit, perhaps once I get proper reading of the battery charge everything will work…. hopefully. Any thoughts is greatly appreciated.

This is a toy for you the Jetson electric bike is my race car is my traveling kit. It’s everything I use to travel to go anywhere if I would have been able to afford a bigger version I would’ve just saved for it, but it didn’t turn out that way, I saw it I bought it and now I love it so I’m going to put whatever I can into it. I’m going to invest in my Jetson. I’m not going to buy any other electric bike.🏍️ So if the money is there to get another electric bike, not gonna use that money to get another electric bike I’m going to use it to make this the baddest Jetson anyone has ever seen. I’m gonna post it and explain how I got it that way, but it seems like there is a jetson family but there are also other bikes that have their own set of families but the Jetson it’s very cheap but it’s very powerful and some people do so understand the power that’s in the Jetson. They don’t talk about the continuous so yes, I really appreciate the upgrades and things that you are doing to the Jetson because it might be something I’m interested in the future. My goal is to stop at a 52 V system great content.

It s the same thing for the jetson bolt pro... Thk u

i have a DYUff500 and it has too many limitations and governess in speed i wonder if i change the controller will it give me more of a boost and higher max speed (within reason) anyone have any idea? if so any recommendation on what controller or any other steps for a plug and play experience?

Anybody have a link for the folding stem please ?

My bike wheel spins but won't carry me just stops any ideas why did replace the back tire

Super curious as to what you did with all of the connections that are on the bluetooth board

It’s the continuous they’re not telling us about our motor

What battery should I get for the most Myers To upgrade

Hello do you know what the charger hole on the bike is called I broke mine

I just Ordered Luna X1 Ludacris w/ Silent.... What do I need to do???

Always unhook the pedal assist to gain speed🫡that's on the pro model 😁👊🏽

will the stock controller/ ESC handle the higher voltage battery ? i think the stock controller has 63v caps so i'm guessing yes.

Did you ever change the 350w hub motor

Can you install pedals on this ebike. Where I live ebikes are required to have pedals.

When's the test ride video coming out? I did the same build, on a 2nd hand D1 dyu bike - exact same bike as in your video. Currently running it at 52V liyon battery @700Wh, a 10A controller 15A peak, and getting ~20-22mph out of it. Still running the stock motor which is out putting 500w continuous, 750w peak. What top speed did you you get on yours? Cheers from UK 👍

Nice! I love all forms of hot roding. :-)

Can you damage your battery by having your controller pull more amps than the battery is rated for?

I have jetson bolt pro. Can you give me a link to 20AH battery and compatible controller that will fit inside the bike? And throttle, and hand grip link?Jetson bolt pro original specs are motor 350W, 36V, 6.0 AH,, charger UL 100-240V

Can i still buy these parts? It says the grow and throw is down.

I would like to purchase the controller but your website link isn’t directing traffic to the Shopify website you mentioned

Wow thats short, the bike? The hair? I’m just not sure but love the video!!

How to turn off the brake light from blinking off and on and get my Jetson electric scooter bolt on the way again

I’ve made a savage DYU it’s got a 60v 2000watt motor I managed to find a 10ampH battery that fits (only just) but the controller doesn’t fit, I have a case for it but my issue is, The battery I got has and XT60 clip & a T-Plug, I don’t know which ones the charger out of the two and it’s driving me insane, I don’t know what to do

I’ve been waiting for this for awhile lol

Does this work on a normal jetson bolt

What is top speed now with the upgrade’s?

Great video cheers mr holmes

Would you be willing to do something like this if you were shipped a jetson bolt pro? as a hire?

I would like to buy one of the controllers. How do I go about ordering one?

Does work on 36 v windgoo b3 e bike

Bonjour! J'ai un vélo Kugoo kirin B2 (V1).. Quel contrôleur je peux adapter à la batterie (48v 7,5 amp) pour essayer d'avoir un vélo plus véloce... Je vais changer la batterie qui manque d'autonomie par une batterie avec plus grosse (~ 16 A) .. Est-ce que une nouvelle batterie 48v et ce contrôleur 48v suffise pour s'adapter où il y a d'autres facteurs a respecter ...? Merci

How much are the controllers going to be? Will they be plug & ride?

Any ideas where I can get the tires?

Salut, comment annuler anti démarrage

More info. :). I want to buy

Hello, what is the name of the battery and where can I order it?

Nice Video sir.

this man doesn't reply to anyone, but if he wants comments

I really want to upgrade the speed controllers on my daughters and my electric scooters I know they are limited in speed and power but I don't know where to find a upgraded controller. I'm about to just put a castle xlx in it. Also if anyone can help me out I'd appreciate it. I'm 265lbs 6 foot and I have two swagger 5 upgraded motor scooters for me and my kid and I can't believe how well it hauls me around at 17mph but I know I can get more out of it so I can keep up with my kid. I'm really experienced with rc electronics but I don't know much about electric bike/scooter controllers and where to get them. Sorry for the long comment.

I want one!

I want my Jetson electric bike to be the baddest. Yes I only wanted to go 30 miles an hour that’s it that is it. I believe anything over 30 miles an hour on this Jetson well I can tell you it’s a very sketchy only because it’s a smaller bike With smaller wheels 14 inch wheels 30 miles an hour yeah I want to safely be able to get my electric bike to the speed of 30. I tested my bike. I’ve written it all over the place. I got to know how to use it what he could do what it cannot do, I’ve reached speed of 30 miles an hour going down very big hills. Praying to God my brakes work of course I checked them before I went down the hill and not the front brakes. Don’t hit front brakes going down really bad big hill so in here, I’m definitely taken so many gave me advice to do a.Shunt mod and I just looked into it and I don’t agree with it because it’s gonna heat up my whole bike and start ruining the wires who knows probably catch up on 🔥 put the shunt mod could work if done correctly just not on😂 my Jetson so I already have 19 miles an hour and it’s been fun so I’m upgrading my battery to 36v 20ah and for now it’s a big upgrade for me thank you for your advice. I could still use some more advice. I do understand everything has to be on the same system so that’s why I didn’t get a 48 V with a 20 amp battery because it changes the system and it could ruin my bike so because I don’t have enough money to, change the whole system, but I do have enough money to last longer and the speed. I’m getting right now is good so when I put the battery in, I already know I’m gonna be going about 2324 miles an hour. That’s good for me and it’s safe without heating up and destroying my motor and my controller.

What controller did you use?

If you have any controllers for sale that are specifically made by you or mod modification made by you I am interested to buy to meet you are professional and it is safe. I trust you.

next video please , thanks

Are you on fb ?

But the real question is... where's Teryl?

I would like to buy one please$$$

Just dawned on me this vid over a year old forget my last comment that bike is probably gone by now

my xiami escooter does 20miles and goes 30mph.

I need more speed...

can you do mine!! 🙂

I have a Jetson bolt version 1 the voltage for it is 36 and the stock battery is 36 volt 6 amp would I be able to upgrade it to a 36 volt 10amp to get more mileage and still use the same controller

6Amph lol the stock is more like 20Amp Minutes

Dude you gotta shave and a hair cut. Now I want soup up my jazzy scooter.

Jetson Bolt or pro is aprox $300. Why spending more in battery than the cost of the bike (the worst recommendation). Better get a much better bike with better features.

Aftermarket controllers are no longer being made, sorry folks!
