Instant e-bike: electric bike conversion kits

[croncong]

Good, I like that you share this video, I wish success always Reaching legal speeds up to 35 mph (though generally closer to 20 mph), electric bicycles are an option for many commutes

[fux7d]

Goddamn it cut your steer tube! :)

[SteVeYG215]

RIP MATT

[dog33100]

gas motors all the way

[fairyheli2]

I don't mind a tank of petrol / gasoline that close to my balls, but lithium polymer, no way.

[FullFledged2010]

@fairyheli2 lipo's dont explode out of no ware. They give you a big enough warning by smoking and bulging before they blow.

If you crash and tear a gas tank its really game over...

That is if you're comment isn't sarcastic of course.

[omar3550]

How did he die? Bike racing? RIP

[suwatintamin]

Woow !!

[eMoped1]

Rest in Peace Matt ... eMoped- endless-sphere(dot)com, really liked your motorcycle.

[bigfoot6433]

damm $1,000 to expensive

[917kporsche]

I hate registering anything, its just a way to get taxed. Alot of ebikes owners are running hub motors, and thats fine, but the use of a chain-driven system is the only thing I'm seeing as worthwhile lately. The majority of the ebike's with hub motors look clearly well equipped (battery-wise) to run a chain driven system. Just think about being able to use the 20mph hub speed through a set of gears! Thats where big speed comes from, I haven't seen a hub go over 50mph, but I'd love to!

Hi, im planning on making an e bike myself- ive recently ordered a 48 volt 1000watt front wheel motor kit- and i was wondering what type of batteries are those: whats the volts and Ah's ???

LOOKING FORWARD TO THE REPLY

thanks :)

[braaup]

Just an idea:

You have the motor in the back hub, why not make a friction-type battery charger out of the front hub to help charge the batteries? (:

[Shiftee88]

I just went to the website and it said that the guy in this video is dead. How did he die?

[kirstendirksen]

@Shiftee88 He died in a motorcycle accident the week after our interview. I also posted another story about his work on electric motorcycles and more on his work and life. You can find it in the video response or it's titled: An EV (motorcycle) visionary: Matt Dieckmann (1981-2010). His death was really a tragedy.. he was doing great work and a really great guy.

[jeepers2655]

@kirstendirksen sad to hear about his death.His bike was pretty fast and powerful.

[minuteman2k]

How much im stupid its all i can ask how much DERRRRR!!

[xxgg]

I sure don't want to place those LiPo near my nut sacks.

[dellam04]

that's very nice! in TX, if it goes beyond 20mph you need vehicle registration...

[xo1tom1ox]

soo...how can I make one and how much ?

[kirstendirksen]

@xo1tom1ox There is more info on the Electric Race Bikes website about what parts are involved and the cost of the different kits for putting together your own bike. electricracebikes . com/e-bicycle-products . html

[superskullmaster]

@kirstendirksen Normal RC car batteries my ass. Those are Large RC aircraft batteries. Don't downplay it. 72/4 = 18V. 18V packs are for larger RC aircraft, especially considering how thick those are, i'm guessing at least 5000mah.

[teamswaim]

I run two 3 cell 11.1v @ 5000mAh Hyperion batts in my OFNA 4wheel electric conversion 1/8 scale buggy. topin 80 plus mph That's 22.2v @ 10000mAh in series. Cost about $90.00 a piece. I'm sure hes got at least $500 in batts alone. defiantly not normal rc batts.

[webboist]

thanks for the reply. Yes its just that if one is fitting a external motor like the rc turnigy range one can get some monster motors like up to 12 000 watts. Saying that one has the problem then of suppling these motors with the power required which in the lithium world is very expensive. I think a motor of 3000 watts is enough though. Dont know whats best though a hub motor or a external motor linked via sprockets etc. Some nice brushless motors on the hobbyking site though

[webboist]

Hi can you inform us how many watts your hub motor is thanks

[kirstendirksen]

@webboist Most of Matt's kits used 400 watt hub motors, though one is listed as being able to operate in the 600-2000 watt range. "The Crystalyte 5300 or X5 motors are the most powerful bicycle hub motors we could find, easily able to operate in the 600-2000 watt power range."

[huntman40]

good old turnigy batteries.. great for ebikes and sooo much cheaper then the batteries on ebay but for god sakes lean alot about lithium polymer batteries before you mess with them.. they can catch fire if mistreated and also easily damaged if you over discharge them

[huntman40]

good old turnigy batteries.. great for ebikes and sooo much cheaper then the batteries on ebay

[tonyoandgunit]

Nice nice, but the batteries needs to put into the frame in order to look good like motorcycles, so this frame is too small for that, and the price is the main problem with all that electric stuff like ebike, moped and e car. For a fast ebike i need to put in 3000$ at least, and for 1200$ i can buy a barely used, about 5years old responsible yamaha 50ccm moped with 2strokes, 60-70km/h max speed and with 2-3l/100km consumerism, which meaning about 300$ gas price/year if we using a moped 5000km/y.

[falk1506]

wow. impressive!

what fork is that on the bike?

[chippymel]

How many batteries did you use at what voltage each and what make are they.

what company did you use.

Thanks for the vid.

[kirstendirksen]

@chippymel Matt was killed in a motorcycle accident 6 days after our shoot, but there is still information on his website regarding the e-bicycle kits he was putting together where you should be able to find voltage and other specs. His company/site is Electric Race Bikes or you can find more info in the link above.

[carrabec99]

nothing like smacking yer nuts off a battery ha ha great bike though

[faheemthedream2007]

FAB video! like everyone says, in this economy, its TOO expensive :(

[0urGaia]

@faheemthedream2007, Only need a cheap $150 bicycle which is often better as their heavier frames can take heavier loads (or get one secondhand for under $50); 36v hub kits can be sourced ebay for $200 new; Lead acid batteries are cheap but heavy and wear out faster. I use 2x dewalts containing lithium cells costing $100 each that give 7-10 mile range, works out 1 cent for 10 miles for electricity/battery replacement costs. So can build electric bicycle for $500 or less

[TheNaughtyBitch]

@faheemthedream2007 I can do 50km and 40km/h for 600 USD withouth the bike ofcourse

[minde28383]

bike looks very nice, such hight voltage makes kit fast, great setup. I would prefer to put batteries lower in triangle to make wight center lower. you are right that full suspension is great when speed increases.

[avaistheone]

Good idea, but I think it is still too pricey for widespread adoption.

[AdamskiAirsoft]

Or you could just use a regular bike... save money, get exercise, be more sustainable, etc.

[mastax1234]

1000 bucks! are you shitting me LOL good luck selling them

[vention4wh]

@mastax1234

There's a market if he can figure out how to tap into it. I paid 1600 for my bionx kit back in 08. I rode it a lot when the gas prices spiked. And when gas gets crazy again I'll be back on it, alternating between the bike and my 60mph/80mpg scooter.
