Diamondback Ebike with 500w cyclone motor part 2

[zaprodk]

Cool bike! - I guess you only have one crank selection since it's a freewheeling one ? I am looking into making an EV biky myself, and i have 21 gears on the bike, but seldom use more than one of the crank sprockets. Where did you purchase the freewheeling crank ? Thanks!

[exaturbo]

@zaprodk

thanks for the comment.

the freewheel came with the cyclone kit.

this particular bike had only one front chain ring.

my current ebike has 2 front rings, and an 11 speed internal gear hub at the rear,

and has a front motor.

my current ride is 48V and is much more efficient than the cyclone ever was.

not quite as much hill climbing ability, but no tthat much less either.

[PaulJunkoKris]

Hey mate, I have the video of the bike on a different youtube account...it's this one.

[exaturbo]

@PaulJunkoKris

got a link to the other video ?

i can assure you that i owned the bike at the time the video was shot, and i filmed all of the video too.

i have since sold the bike to someone else, and moved on to a much more efficient (and powerful) ebike.

[Sageh44]

hi, nice bike, where did you get the bar that the GPS is attached too?

[exaturbo]

@Sageh44

hello.

thanks. the yellow gps is mounted using the standard mount that came with it.

the cycle analyst is mounted using a topeak bar xtender

[Sageh44]

@exaturbo Thankyou, I am just about to start an doing my first ebike 48v 500w BMSbattery kit, one more question if you dont mind, your battery bag what is the lengh of it? My battery is 36cm long and ive had a hard time finding a bag it will fit into.

Thanks again

[exaturbo]

@Sageh44

the bag on the rear is exactly the same size as the battery.

it came with the battery when i bought it.

my new 48V ebike has an even bigger battery.

im working on a way to mount the battery inside the frame (triangle area)

[kauaikit]

Nice setup, though if your going to "cheat", why not a 1K watt motor backed by 72V's?

So, what genius is responsible for the 250watt limit, a Nazi?

What's the noise level with this motor & chain setup?

[exaturbo]

@kauaikit

im about to start building a new ebike.

this one will be substantially more powerful than the first.

ill be running a ezee hub motor on 48V

have to be honest, there was a fair bit of noise assosiated with the mid mount motor, but it really didn't bother me that much to tell the truth.

the 200W limit imposed on us by the australian Govt, is ridiculously low.

i personally would not even bother with only 200W. the diampodback at 500W was only just adequate. cant imagine 200W

[psychowolf666]

i saw some comment and ive see thath they say the motor is directly linked to the weel so the motor run alway if the weel turn?

if y have good read, this is not good use of energy, when moto are runned from the weel, some voltage is created (i know not amp is used if regen is not running

but best idea is to use some hig voltage caps like 100volt and a clutch to desconect motor from weel, an when un want to literali mega break fit the first speed an got of the clutch,

[exaturbo]

@psychowolf666

the motor runs a front free wheel.

this allows the motor to not turn if you are peddling.

it also means that if the motor is running, the cranks do not have to turn.

and it means that you can have motor and peddling if you want.

this was a very efficient set up.

[IcechickenSr]

Cyclone has some extremely SWEET kits don't they. I wonder if the hub style is more efficant than these traditional style motors. I am thinking of getting this kind you have here except the twin or maby single 1500 watt versions so I can go 80kmh for a quick streach to get onto the smaller roads and then cruise at a nice 40kmph. What I really want to know is how much do you get back through the regeneration feature? and dose it work like a break, and come on every time you get off the throttle?

[exaturbo]

@IcechickenSr

with the cyclone style kits there is no regen possible,

as the motor has a freewheeling sprocket on it. as soon as you get off the throttle, the motor stops.

if you want a system that features regen, you have to have a direct drive hub motor.

my next build will probably be a 1.5kw geared hub motor driving the rear wheel.

it's just so much simpler to install and set up the hub motors than the mid mount types. as for efficiency, it depends on where your riding (terrain).

[exaturbo]

@IcechickenSr

direct drive motors are probably best suited to flat ground and small inclines only.

once you start getting into hilly terrain, the mid mount are great, as you can change gears to suit the conditions.

the geared hum motors are somewhere in the middle.

[AtvProjects]

Hi, Is this a Kit or did you make this yourself, I really like the Speedometer part of it. the motor hook-up looks really clean

[exaturbo]

hi.

the motor and controller is a kit available from cyclone-tw(dot)com.

the power usage and speeedo is from a little ebikle place in canada, ebike(dot)ca

[AtvProjects]

Thanks:)

[popoqwer]

24v 18ah ... is that the real rating of battery

thanks

[exaturbo]

Yes, it was an 18Ah battery, however the Ni-Mh battery was NOT really up to the job. it suffered from a lot of voltage drop under load.

so it was replaced with a 24V 20 Ah LiFePo4 battery that works fantastic, and even at 40A load, only shows 1 - 2 volts drop. it was not cheap, but good power isn't.

[electrifyme321]

Is there an alternative to the Cyclone that

gives you the mid-drive? At +$1000 the

Cyclone is steep but I do like making use of the bike's gears.

[exaturbo]

not than i am aware of.

check ebike (dot) ca and see what they have on offer.

[electrifyme321]

How should a person decide on what size motor to buy?

Now that u have had this experience do u recommend this kit and any particular motor size ....any controller.......any battery... anyone elses kit or motor or would u use a hub motor?

[exaturbo]

if i wewr to do it again (and i will someday) i would still buy a mid drive setup, as it's much more flexible in that you still have the benefit of gearing.

i would probably go with 650W+ motors though, maybe even 1kw. 500W was ok, but at times you want more.

hub motors are easier to install, and are more efficient (less parts) but its mid drive for my money.

Jason.

[electrifyme321]

Your video clearly shows that the motor is 200w. Why are you saying its a 500w?

[exaturbo]

i had the 200w stickers made up, as its not legal here in oz for anything greater than 200W.

the motor was 200 watts (i have since sold the bike)

[lemongreat]

coooooooooooool

[trumpettom001]

Why do you have a GPS, is it for navigation, or very accurate speed measurements? how easy is it to read when zipping along?

[exaturbo]

the gps was just for speed and distance measurements. very easy to read at speed.

[eddiequest3]

You've obviously put a lot of work, time, and money into this project. I congratulate you on your efforts. I can't wait to see some numbers and notes on performance.

[exaturbo]

thanks, i appreciate the comments.

as for performance, ill have to get off my but and do some more videos now that i have the LiFe Battery system. it "Dumps" on the NiMh big time as far as usefulness goes.

top speed on flat ground with zero human input is about 42kmh in 9th gear.

with peddling, it's a little faster.

i have seen 64kmh down a big hill in 9th peddling flat out. (that was fun !)

average speed on my trips is about 30kmh and at that speed, i can go about 40km on one charge.

[bobebobebob]

how much did all this cost you? and what kind of camera are you using?

[exaturbo]

all up (including the bike and all the extras like the lights and new tyres) it owes me an astonishing $4000 AU.

the camera used on just about all my videos is a sanyo Xacti HD1000 Full HD digital video camera. recording at 1920x1080i.

[franccis94]

what is the black box with the green screen

[exaturbo]

it's called a cycle analyst, and it's available from ebike(dot)ca.

it's basically a sophisticated dashboard for electric vehicles.

[moss1transcendant]

hey thats great thanks for showing the menu screens on the CA ive been searching for awhile for that.

[exaturbo]

no problems.

if there is something specific you want to see, let me know.

i will try to film it and post it up.

i am going to try to get some video of the screen while im riding, so people can see what it displays.
