Hi,

Just joined as got interested again building my very first pedelec.

It as Specialized Sirrus Sport and wanting to fit a front hub.

the fork is tapered, not easy to find a front hub motor for it.
As soundwave said, it would be better to fit an 8-Fun CD kit

[SpezElec]

do you mean that I cannot fit a 250w front hub on my fork?

 

[soundwave]

yes i think that what trex means thus link to the mid drive.

or get a fork that will fit the hub drive you looking at

 

[SpezElec]

mid drive is complicated and expensive,need to research more on these,

thx

 

[soundwave]

its 100mm on the bafang site width wise for front hubs few bit wider also.

 

[SpezElec]

i know hybrid bikes has tapered fork but I measured just now and have 100mm dropouts,and the website I am planning to buy states 100 mm clearance is needed, so cannot see why cant fit,I seen a video of someone fitting a front hub on a dillinger bike on you tube and it was compatible.

need help and clarification on these pls, can a Spez Sirrus Hybrid Bike fit
a 250w geared hub..thx

I see no reason why it won't fit to your bike with a standard 100mm width.

Just be sure to fit the 'c' washers and torque arm. The kit includes them, scroll quarter way down page to see:

It depends on how fast you want to ride.
If you only want light assist then it's OK, you can fit the 120mm 8-Fun SWXU motor for example but not the larger motors such as the 128mm 8-Fun SWX02 because the casing will foul against the insides of the fork.
Small motors of course give less power. For faster speed, you would need to replace the fork to accept larger motor, hence my advice to go for a crank drive kit. Watch the video, it's much easier to fit than a hub kit.

 

[SpezElec]

nice...I hope it fits,waiting for the seller to reply,guess he is on holiday

 

[SpezElec]

cant fit anything more than 250W as staying legal as mostly will be using the Spez on roads to increase AVS,imagine if I can maintain at least 200W on a 1 hr ride,will probably give me 18-20 mph,pedal assisted

SpezElec has mentioned that he's on a budget. A BBS01 will almost double the price

 

[soundwave]

no 1 has been pulled over on 1 yet and had bike taken off them

i doont even take my dongle off my bike as never had a problem with police.

up to you tho.

How many members ride an e-bike with 200W power?
I'll give the OP two weeks before he'll want to go faster with his Sirrus.

 

[soundwave]

more like 2hrs

 

[SpezElec]

oh man, do not tempt to get a bigger motor yet,this is my first build,I can maintain,15-16 mph on flats and 13 mpd AVS on hilly route,a 250 watts motor
producing 150 watts extra power considering the weight penalty is a lot me
to play with,,I think

 

[SpezElec]

plus I hate being pulled,I do not want to be the first one.

 

[soundwave]

you can get 6000w hub motors
