I forgot you'd changed tyres from the original ones - 60 psi in the originals would be well above the limit. Is there a possibility your front roller brake is binding a little? Have you loosened off the cable to ensure this isn't happening. I've never counted the number of free spins I get out...

I'm surprised to read that John. My identical bike is quite pedalable on the flat in 5th so I'm wondering if fleccs comments about tyre pessures may point in the right direction. Both tyres on my bike are pumped to 45 - 50 psi. I dont find the ride to harsh because the suspension seat post and...

Those are some of the factors (although its not a case of multiplying them altogether, it's just they're relevant). Other factors which jump to mind are the gearing ratio of the hub (assuming it is geared) along with the frequency of the electrical supply from the controller. You'll see from all...

Since we've discussed batteries before (I think it was via pm), you're already prepared for the price shock (£250 RRP down to .... whatever you can haggle them down to - ask them about a 9Ah one, if they can still get them). I was considering doing the London to Brighton ride last year but I...

For a given power output a higher voltage motor will tend to have a higher number of windings but what matters is the strength of magnetic field and although the lower voltage motor will have fewer windings, those windings will tend to be from thicker wire so the field strength is still there...

Watts = power I think for the sake of clarity it's best not to even refer to voltage (unless with reference to overcomming resistance losses in long cable runs) as it's the power (in Watts) that matters (I would say entirely but things like design efficiency come into it as well). For those not...

It depends where in the USA I was reading this Electric bicycle laws - Wikipedia, the free encyclopedia all about electric bike laws and as you'll see the results vary widely and in some places they're strictly forbidden, with riders being subject to arrest eg NYC - I dont know how that stands...

As long as people realise the 5 speeds only relate to the input sprocket gearing - from the pedals so in that regard the whole assembly has 5 gears but the motors, unfortunately only one fixed gear.

The only way that would have helped is if it was de-restricted as he was way above 15 mph and as this part was on a road and I'm not that naughty (well at least not in that way :eek: ), that was a no no. Additionally, I should have mentioned it was a long hill which wasn't gentle so there's no...

Either your tyres add a few mph to the speed of your bike or you're better at egg beater leg action than me, 26 mph is really some achievement on the flat for a similarly geared Twist. I don't understand, isn't that what the eco or power off settings are for? ie if you want more exercise, you...

You're correct in that it's not a drive through the gears system and the motors are only connected to the hub through a compromise fixed gear ratio :( seems like a lost opportunity to me given the gears are already there in the hub. The Sparc has been around for ages now, I would have thought...

Sorry Andrew, you're correct flecc, it was a blonde moment. The rest is correct about the motor being the same brand. It does make me wonder why they stepped back to 24 V, especially with the additional resistance of the long hub motor supply cables to deal with.

I was thinking the increased power would be nice specifically for hill climbing, there's little need on the flat and I often go in Eco or power off mode on the flat anyway. The 750 Watt rating is only the maximum power that the motor puts out, this doesn't mean it has to draw that much all the...

I only have the Dutch manual and AtoB review to go on but yes it's 36 V and it looks to also have the same brand Sanyo hub motor. Perhaps the chargers for the NiMH version (Twist 2.0) may be similar to the Suede's as well?

I guess what I'm wanting is something that'll go up hills faster and although the Twist will go up even the steepest, its 240 Watt motor (check your workshop manual page 1-1 if you want to confirm that) doesn't allow this to be done quickly enough. Maybe it's just that I was overtaken for the...

Very well put John, I concur. I'm also perfectly happy with my Giant Twist Comfort and this is one reason why. If I'd done yesterdays 19.5 mile journey from Reading on a bike with the option to not have to pedal, I suspect I wouldn't have got anywhere near as much excercise as I did. If I wanted...

It looks as if at least one of the latest Giant Twist (hub motor powered) bikes has a charger with a fan so at least they're going to the trouble of considering thermal issues, not something that can be said with certainty about all electric bike manufacturers. If the fan output has deteriorated...

I'm not being funny here but the Suede charger is a different kettle of fish to the Twist one. The Suede manual shows the charger for that bike has a fan, the Twist Panasonic chargers on the other hand do not. Does your charger contain a fan or does it differ to whats in the manual? If there's a...

Looking at the picture in the manual it looks more like the older ones were coated rather than submerged - certaily the one I have has the components fully submerged and only wires emerge, thats the difference in terms of heat. As you mentioned and as the change in part numbers suggest, there's...

Well the charger I have (which is a Panasonic NKJ019) has the components deeply submerged in the stuff as opposed to the picture of the older EKJ006 in the Twist workshop manual page 6.2. I think its an issue of the extent to which the components are coated - with fully submerged parts having...
