Spontaneous Combustion or HUCCS Disease?

[vectra]

Electric Transport Shop has a Storck Raddar bike on sale on Ebay. Item 180918877840. Could it have combusted spontaneously or might the last rider suffer from HUCCS disease?

Either way it would be a brave soul who took this on. Probably need a visit to the shop to really assess the possibilities, if any.

It looks as though it was an external fire, rather than the bike itself combusting. It looks in quite a mess though, and getting repair parts could be a real problem.

Hi Flecc.

I'm no epert on HUCCS disease however with my insignificant knowledge this fire could be classed as external?

Hi Vectra, I've always been a cynic about the existence of human spontaneous combustion, ranking it with ghosts and cold fusion, so I was discounting that as a factor. A bike cover accidentally set on fire could have been a cause here, burning the saddle and wiring and making a cosmetic mess.

Mass spontaneous combustion, or so it seems.

It appears there were a number of machines in this building which caught fire, one of them being an UltraMotor A2B Hybrid which is now in my workshop. Evidently the machine was brand new, and still in it's box when the building caught fire, but in the case of the machine which I have, the damage limited to the front control cables and wiring. A nice little restoration project for the winter months.

Of particular interest to me, is the use of the TMM4 torque sensor on both of these machines, as opposed to the archaic rotation sensors normally associated with hub-motored machines. Should independant throttles be banned under the up-coming changes to the legislation, effective torque sensing will need to be adopted to ensure the continuing popularity of hub-motored systems. Without such improvements to their control systems, the Chinese hub-motored machines will lose an even greater share of the market to the more sophisticated center-drives such as Panasonic, Bosch and others.

Hmm. Next you'll be telling me that Rick Spleen doesn't exist either.

I know he has a sort of existence since he's my brother's favourite comedian.

But I still had to look up Rick Spleen on Wikipedia to know who you meant!

Yes indeed. What will be interesting is how much the forthcoming Chinese crank centre drives affect the market. We've had a two decade fight between crank drive and hub-motors, see-sawing either way first in favour of one, then the other and then back again. This might just be the start of getting a final winner for the majority of e-bikes in the way that front wheel drive transverse engines now dominate the car market.

The MPF drive is the one to watch

Yes, the computer control of power level to match the circumstance in addition to a torque sensor could be ideal, though I doubt it is necessarily an advance on the Bosch unit. It still has the obscure legality of present systems as well, nominally 250 watts but capable of continuous excursions to double that. The European Parliament's move to do away with power limits is what we really need to free up designers of such systems and open the market right up.
