Haibike Bosch 2014 motor protection

[triumph_st]

The new Haibike E MTB's have a neat motor protection shield mounted under the 2014 Bosch motor. Is this shield for sale as a spare part (to be mounted under a non-haibike)

 

[EddiePJ]

Aren't the Haibike motors inverted by 280 degrees and placed above the frame tube. This being the case it won't have one.

I can't be 100% sure whether it's a genuine part or not, but I think that Cube might sell them as an accessory for the Cube Stereo Hybrid 140 SL 27.5. (now there is a rank hideous bike if ever thee was one)

I couldn't find it using Google, but I know that I have read an advert for it in one of my MTB mags.

Failing that, just make one. It's hardly difficult.

There's shield on this bike in the forum's for sale section.

But as Eddie says, it seems pointless with the motor mounted above the downtube.

The new Bosch motors are not inverted, the new design makes it unnecessary.

Right; it is for the 2014 Performance motor and they are (and can not be) inverted.

This is what I mean

Mine is protected by a layer of mud, it has sound deadening properties too.

In- or outside the motor?

Only the outside, the Belgian Pavé shakes the other away.

Focus have done something similar with the Thron electric ATB series, the Impulse 2.0 motor is tucked away above the downtube

surely putting the down tube under the motor just means you have loads less clearance?

whats the clearnce on this bike? and more importantly whats the actual point of mounting it above the downtube?

Sufficient

To achieve sufficient clearance.

Hi Col,

The Gen1 Haibike has the motor mounted above the down tube, this gives maximum clearance and keeps the motor protected.

But that is off topic as the thread is about the Performance Motor mounted on the Gen2 Haibikes.

The simple answer is No. The haibike has a hinge built into the frame. This means the skid plate cannot be mounted onto other eBikes.

It's really neat actually, once the two bolts have been removed at the front it flaps down for easy access to the motor.

hmmmm, not overly helpful.

I was hoping you might be able to help explain the point of mounting it like that, because from an outsiders point of view, it looks like you're going to end up with loads less clearance, or a crazy high BB axle which will mean crap handling and a worse centre of gravity than a standard system.

It also seems to be attempting to solve a problem that doesn't exist.

Hence why I'm asking what the point is?

thanks for that Martin, much more helpful.

If you mount the motor above the downtube, surely you actually get less clearance, or a crazy high bb axle. It can't have more clearance and keep the bb axle nice and low?

Cheers
Col.

 

[Martin@e-bikeshop]

Nope, on the Gen1 it is perfect. Gives good central mounting of the BB axle and gives approx 3inches more clearancecompared to other non inverted Classic line motors.

Also brings the motor out of the firing line from all the crud that flies up off the front wheel.

If you want more info search google for - 'Why Bosch eBike motors should not be under swung'

Seems to work in practice

Thanks Martin...

Tim, you're still not really answering the question... but nevermind.

Martin, can you measure the bb axle to ground distance on a 29er hardtail with one of these systems, so we can compare. Because I can't see how you can put a tube under the motor, and not either decrease clearance, or raise the bb. I don't see how you can get 3" more clearance and not actually riase the height of the bb axle.

I'll have to have a better look at the geometry charts, because I'd not really considered this until reading these posts tonight.

Cheers

Col,

The Classic motor is egg shaped. The bolts sit within the top of the Haibike frame.

Whereas on yours the motor sits underneath. But is raised into the underside of the frame. The BB axle stays in the same place but the Bosch motor gives loads more clearance inverted up into the frame.

In my article here - http://www.e-bikeshop.co.uk/blog/post/a-little-bit-about-haibike-and-why-they-are-different/
Amongst other things I detail a little more about the motor being inverted.

Col, why don't you visit Martins shop and try one for yourself. You can even take your tape measure with you.
