Specialized BigHit + Cyclone 1200w

[dave.a]

Hi guys, thanks for the comments! Specs for the bike are :-
Maxxis minion 24"x2.7" tires front and rear on Halo Combat rims and DMR Hubs
Hope 4 pot rear brake with sintered pads and Hope 203mm floating Disk
Large single pot front with Hope 203mm Disk
Marzochi Shiver forks and Fox DHX 3.0 ( to be replaced with DHX 5.0 Air)
SRAM X9 Derailiur and X5 shifter, 34-11t cassette and Powelink chain.
Motor connectors were replaced with 4mm golds and battery conectors are EC5's.
Chainring sprockets are Dmr 32t inner and 42t outer. I used the original cyclone outer ring as the mounting plate for Dmr chainrings.
Ive still got a fair bit of work to do to get her how i would like, inc frame box for the lipos as mentioned, rear shock changed, the controller is boeng moved further down once my mounts are finished for the fork tubes.
Ive already stripped the gearbox and re lubed with high temp lithium grease and i vaselined all the cable entries from the inside.
Timma's bike really inspired me aswel, and i defo agree it is THE best cyclone build ever!
I built this as a fun bike, not a commuter, all my trails are about 500m from my front door, so getting caught in the rain isnt really a problem, i just wanted a reasonably powered, light as possible 'attack' bike it does the job spot on.
Ill keep this thread updated with photos and videos will come as soon as ive registered and figured out youtube!
Im in Nottingham and would love to meet up for a ride with folks, just need someone to organise it all, how about you Tench
Cant wait to see your HS big hit!!! Its going to be awesome.
I usually see peak Watts on this of around 1800w by the way, is that avg?
Cheers Dave

You lucky bugger, i've gotta drive 60km to get to my fave trails!

Yep, 1800w peaks are about spot on with a 8ah lipo pack, i got the same when i ran a 10ah pack.
Funny enough i now see around 1900 - 2000w with my 15ah pack, less voltage sag i guess as peak amps are still the same at slightly over 40a. I'm going to try to beef up my shunt for around 2500 - 3000w soon

How do you find the 2.7" minions, do you like them?

Whats yourtop speed on this monstr? Love the build!

[dave.a]

The max amps ive pulled so far is 36A. Top speed is around 30mph ish. Its geared for off road and steep climbs, which it does really well.
Videos will come soon
Timma, the 2.7" minions are an excellent tire! Quite good rolling resistance aswell on the road. Ive got the 60a on the rear and the super sticky up front.

[Timma2500]

Thats interesting your getting 30mphish while mine pulls up to 40mph wound right out in 9th gear. We're both using an 11-34t cassette and a 32t on the cranks, your using a 42t from the motor on the crank and i'm using a 44t and we're both running 12s lipo. It must be the rim / tyre diameter that makes the difference perhaps? (24" vs 26")

They sure do climb well. There is a hill where i ride that i've dubbed "c#nt hill", its the sort of hill you'd never get up on a normal un-powered mtb and i struggle to keep a balance of controlling wheelspin and keeping the front end on the ground its that steep, yet the cyclone chuggs up it with no complaints (apart from heating right up by the end of it lol).

The combo of the hard 60a rear and super tacky front 2.7" minions sounds great. I know what i want from Santa this xmas now!

Anyway back on topic, vids when you can!

looks awesome! got a link for where to buy the cyclone 1200w?

[dave.a]

Timma, 30ish is just a guess, as i have no working speedo on the bike yet due to mounting issues with the usd forks. Ive milled off loads of the controller case fins and that only ever gets barely warm. This made it look a little neater and shaved off 300 grams. The motor only ever gets warm to the touch even after hard uphill stints, i think thats down to all the brackets acting as heatsinks. 24" vs 26 does make quite a difference, i much prefer 24's.
I got my mates motor kit from Eclipse bikes in the uk.
I am planning on selling the mounting kits for Big hits if anyones interested, or building full bikes for people if they want them.

[Tench]

Hi Dave, i used to ride the trails on enduro bikes before they where all reclassified, i know most of the peak district trails by heart and a friend has all the OS maps for the country marked up with a the trails high lighted, where ever you want to i can get the trail maps! We used to do a 200 mile round trip to Manchester and back nearly all on the trails, i know the ebikes cant do this but i can still put a few good routes together for some days out in the peak district if you fancy it? maybe a bit of a group ride UK next summer?

Simon.

[dave.a]

Simon, that sounds spot on mate. There is 3 of us that would be well up for that! So thats 4 so far! Im sure we could get 10 plus

[deecanio]

Definately up for a ride with you guys next season, also let me know wabout the big hit mounting plates

[M1k3]

Lovely build would love to see action vid (even though ive never done one myself) I have built a similar bike kona stinky based,I am still impressed every time i use it ,Offroad this setup really works well .enjoy

[kmxtornado]

Wow, that ride looks amazing! I love all the color coded stuff and you got my color scheme. Sweet! Thanks for loading the riding pics too. Nice to see it in action. Congrats by the way on your first build. That's quite a piece of work. I just finished my own not too long ago too.

[Craigh85]

Hi dave bike looks great hope you post some vids, the more i see these mid drive setup's the less i want a hub motor. They seem the way forward for offroad use. I have a big hit i was hoping to do my first build with looks slighty diffrent from your frame think mine's is a bit older, looks rounder! does that rule out your mounts? also was looking at cyclone stuff the other day, a guy is selling very small 50v 45amp controllers for these have you seen them? look similar to rc controller, mabe they are i'm not sure am new to the scene lol.

About the trails near Manchester. I am based in handforth. Built two dh bikes so far both with frock motors. Will get to a decent mid drive one day. But anyway +1 on some manchester/ peak district trail riding
Regards Andy

[dave.a]

Hi all, just a couple of pics to show the new contoller placement.
Much better now



Almost finished the frame mockup for my welder man aswell.
It will have room for all the wiring and 24ah.
Oh yeah, pick up my bomber saturday morning aswell

[deecanio]

Oh yeah, pick up my bomber saturday morning aswell

First dibs on the BH if you sell

D

[dave.a]

I dont think ill sell any time soon mate, its my first baby
Had a good ride today after picking up my Stealth Bomber from Tench. A friend used my BH and we went gor a muddy play! The big hit performed faultless for another 12 miles of hard use!
The Bomber is on another level though! Not got any video yet as im waiting for a handlebar mount for my iphone 4s, should get half decent videos with it.

[GCinDC]

you are officially killing me.

[waynebergman]

How do the two bikes compare in weight, top speed, range, hill climbing,smoothness of power, & noise levels?

Any chance of showing us some video of the two bikes tackling a small hill climb and letting us hear and see them work? Would be awesome if you have the time?

[dave.a]

Its abit unfair to compare them like for like really. Im going to sort videos out on sunday, with plenty of hill climbs.
Will give more of a comparison tonight when im not at work

[Thejammiedodger99]

Finally registered mate. We will get some vid for here very soon

[deecanio]

viiidddddddddds

[dave.a]

About time!
Mr dodger is my mate with the blue BH

[Tench]

I hope you have cleaned that bike!!

[grindz145]

Vids or it didn't happen.
