August 8, 201411 yr Author I expect you will soon learn to multiply by three, after all you only need to know the speed within an mph or two. The battery indicator bars still works as they should. I think they are better, because the range number goes up and down depending on the loading on the motor at that time. The Bosch system does seem to throw up the occasional error message. From memory, mine did it pre-dongle, so I doubt it is dongle-related. I take it you know you cannot turn the system on if there's any pressure on the pedal.
August 9, 201411 yr Good stuff. Yep the battery bars, seem like a more reliable indicator. Very happy with it all so far. Very expensive compared to a normal pedal bike... but I guess we are "early adopters" of a new technology (even though Pedelecs themselves have been around for ages) and as such have to pay a premium. I am feeling fitter and stronger after a week of cycling to and from work. Certainly sleeping like a log too. Thanks for all the advice.
October 2, 201411 yr I've just fitted the badass dongle today, so far so good. As you say speedo isn't accurate. It seems it gets up to 10mph then drops down to 4mph upwards to about 9 on the unit, can't seem to make it much past that but maybe i need to hit a few downhills. Are we saying after 10mph you X3? so 5mph is actually 15mph? Does the range lie as it thinks you have more in the tank than actually do? I guess this won't really decrease battery life, if you're doing less than 16.5mph anyways most of the time you will be using the same battery usage as before?
October 2, 201411 yr Stick a bit of tape over the speedometer section. Whilst you are looking at it you are not looking where you are going. Sure, record your speed on a gps unit for interest when you get home but I don't think the distraction on the road is beneficial to any rider.
October 2, 201411 yr Whilst we are talking about dongles has anyone tried or heard of a mechanical device ? I'm thinking out loud hear ! It should be possible to mount the magnet on a rotating disc or something similar! made in a way that there's only two possible positions. The disc could be turned by a pin mounted to the frame stay, with each wheel rotation the disc moves to one position and then back to the other on the next rotation. Effectively the sensor only sees the magnet every other rotation and the cutoff speed is doubled.
October 2, 201411 yr Seems reasonable _ But be prepared for the avalache of threads... "I have this clicking noise..."

Effectively the sensor only sees the magnet every other rotation and the cutoff speed is doubled. Perfectly feasible but I think much experimenting to get the cam arrangement would be in order. Something similar to the old fork mounted mechanical mileometers. I'd rather go to work, earn some money and buy a dongle. Maybe one for the retired folks.
October 2, 201411 yr Maybe one for the retired folks Or the perpetual tinkerer Personally, I don't want/need a higher cutoff, but the mechanics of it intrigue me.

Mostly agree, although there are places where you do need to know your speed. I cycle through Bushy Park in SW London which has a 20mph speed limit. This is enforced, and you will sometimes see a police car waiting at the end of the very long straight road with a radar gun. Michael

Michael I think most cyclists should be able to estimate their speed within a few mph. The more speedos in the world, the more speed limits. What follows next is then a host of fines for knowingly ignoring those limits. Radar guns in a park, whatever next.

What follows next is then a host of fines for knowingly ignoring those limits. Radar guns in a park, whatever next. The 20mph limit there is a relatively recent event (maybe 3 years or so?). The road is so long and straight that it does encourage drivers to go too fast and if the police hadn't occasionally parked there I think people would just completely ignore the limit. I find cruise control (in the car) to be very useful there - slap it on 20 and I don't have to worry.

I thought they could only charge you for furious riding. I suspect they wouldn't bother unless you were going ridiculously fast, and it was either downhill or you were on a seriously illegal e bike.
October 3, 201411 yr I have no idea John. However they do pull over cars and motorcycles for going too fast and a cyclist overtaking the flow of 20mph traffic would be a bit conspicuous. Mind you, I can only hold 20mph through there on the road bike with a pretty decent tailwind!
October 3, 201411 yr mfj197, my misunderstanding. I thought you were talking about a cycle path and not a road. Loads of 20mph signs have appeared around our area recently. Makes not a jot of difference to motorists. Everyone still drives at 30.
October 14, 201411 yr I must be miles out here, but how hard would it be to reset the bike for a smaller wheel? If my 29er was set to 26 wheel size for example....
October 14, 201411 yr I must be miles out here, but how hard would it be to reset the bike for a smaller wheel? If my 29er was set to 26 wheel size for example.... Can be only done by the Manufacturer using Diagnostics. On the early systems you could move the magnet and sensor to trick the system. Bosch worked this one out pretty quickly.
December 17, 201411 yr Has anyone tried the following speed de-restrictor off eBay? http://www.ebay.co.uk/itm/161508247155?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT I've messaged the seller but he's not giving me any more information on how this works! I'm thinking it must be a mechanical device...
December 17, 201411 yr It's probably the same as the Badass one. A simple microprocessor reads the speed sensor and pulses an output to a coil . It sits between the sensor and the magnet, so that the Bosch sensor only sees the pulse from coil, instead of the magnet.
December 18, 201411 yr Just had a look at his feedback... Looks dodgy to me. It looks OK to me. What have you seen?
December 18, 201411 yr I may be getting a bit paranoid, but..I tend to compare other eBay sellers with my own experiences before buying from them, and as an eBay seller that manufactures and or buys to sell for profit then the law is clear in that I must be registered as a business seller with all that that implies If the law is different in another country then eBay's own rules are also clear in that business sellers must be registered and offer a 14 day money back guarantee and his feedback shows he has been selling the same item(s) in bulk volumes so he is obviously not a private seller disposing of unwanted items. But apart from any legal stuff that may or may not apply in Cyprus, any seller offering a new item costing £80 ish, that specifically states "No returns accepted" suggests I may be risking my cash... All my products offer a money back guarantee, so I ask myself. why would I not want to offer this guarantee?...... As it happens, as an eBay registered business seller I do not have a choice, unless of course I decide to masquerade as a private seller....... Another sign of a good seller are answers to questions.. Being clear and to the point when asked...
December 18, 201411 yr Just messaged seller for more info and realised there is no photo of what is for sale... Is anyone planning on buying one?
December 18, 201411 yr It's approximately the same price as the Badass one. Badass have shown themselves to be trusworthy and responsible, so why not just get their one?
December 18, 201411 yr Author It's approximately the same price as the Badass one. Badass have shown themselves to be trusworthy and responsible, so why not just get their one? Quite. What's the point of pratting around with some dodgy ebay seller when the Badass product and service is so good?
