Yes I can see the irony in it but there is another consideration. Security. & Safety. In the old days of expensive ever ready batteries and lamps and vigilant police, the built in dynamo on the more expensive bikes gave a reassurance that there would be lighting. I would have put a bottle...

Hi you don't need to wonder. Your kinetic energy is 0.5(your weight +bike weight) x speed xspeed . If using kgms for weight and metres /second for speed then your energy is joules . I f you want to convert that to watt hrs it is joules / 3600. A number of the us sites refer to...

Hey d8veh, you winding us up? A dynamo will be a load of say 6w , the bottle type tyre friction ones more and hub ones less. The assumption behind this design is that work done by the motor on front wheel in propelling the bike generates free energy which the backwheel absorbs and charges...

Well we are guessing as to the actual size of these SLA batteries. I was giving the benefit of the doubt that they would be up to 20 Ahr. But the author did refer to another bank of batteries. . You may be correct in that the author referred to changing batteries at about 30 km.

I might have expressed it better. That the chain is stationary is not an absolute requirement, however the hub gear should not be under pressure otherwise the internal gears either will not disengage or will suffer greater wear when engaging. This is similar to trying to change the gears in a...

I have the Motus which uses the Bosch active motor and the derailleur gears rather than the hub type. The derailleur gears expect the chain to be moving when changing cogs. The gear change is very smooth , presumably the motor senses that there is no load and reduces power during the...

I Was the person who suggested that a Raleigh could be purchased with a bigger battery up to 500whr. Of course this would mean a discussion with the shopkeeper before purchase. As the cost of the Bosch battery is very expensive, the idea of carrying two seems to me over the top. It would make...

Basically you are demanding that the shop take your unsubstantiated word that the lever arm was not damaged by you or while in your possession , otherwise you will black mouth this shop. Moreover you will do it in a forum, in the English language , where the users are highly unlikely to be...

Hi my situation is similar to yours I am retired and only 5 years younger than you and prefer to cycle than walk, the scenery changes more quickly. I am enamoured with the Bosch system on my new Raliegh Motus and can recommend it. (See other posts in this forum.). While it only has a...

Hi Hi Scott, my understanding is that your contract is with the retail shop and they are required to sell goods suitable for the purpose. If there was a manufacturing defect , whether it occurred in the factory, or in the showroom, is irrelevant. . The process normally is that the customer...

About the position of the sensor . The magnet on the spoke has to be offset with respect to the mounting screw on the sensor. Move the magnet Towards the rim by about a finger knuckle from the mounting screw. There is a line etched on the sensor housing denoting the correct position.T he Bosch...

And I would fully agree with your statement about the brakes . They are a dream to use.

The Motus does have a suspension saddle post . I found that it has become more compliant with use. If you press down on the saddle you will see the shaft moving slightly . Glad you are enjoying it.

Perhaps we should just stop posting on this thread. Some of the more recent comments by esteemed members are becoming close to libelous. We have had ample opportunity to come to our own conclusions and the OP has had an opportunity, had he wished to respond.

In practice there is no reason not to do so. In theory you are putting more torque on the ball hitch as the weight is now further away from the fulcrum. But against this since only one bike is being used there is less downward pressure anyway. I have found that the locking screw makes a very...

I used maplin audio cable . The type intended for those incredibly loud subwoofer s in adolescents cars. These woofers are typically 3 ohm and the cable is intended to have a very low resistance perhaps 1 to 5%of 3 ohm. so very thick. Cannot remember the gauge, but you buy it by the yard

Hi got a Motus 2 weeks ago and am at 200km. I am promising myself to write a review of it. Basically it will be hymn of praise . It is very comfortable, great brakes , the Bosch active 2 system is very refined. Altogether a premium product and makes travelling at approximately 26km / hr...

I had hoped that by now the OP would have done the decent thing . D8ev you have been an excellent advocate for the OP and it is understandable that someone from outside the retail system may have started off on the wrong footing, but a fool's pardon lasts only so long. David, I am reminded of...

Hi I have been reading this thread from the beginning with an increasing amount of incredulity. If even 60% of what David has said is true, then I would suggest that an apology from the OP is in order and he should man up. I can accept that ,as Dave has said ,he might have felt threatened in...
