Surely the torque figure they give will be the maximum they can get away with claiming and its its at the crank the only way they could increase the torque is if the rear cog is larger than the crankset chainring, i.e. 50T rear cog and 42T chainring which would increase that torque figure. I...

The 4% is taken off after the drive ratio calculation. 34/42 *50Nm minus 4% It was only a rough calculation in my head, basically it looked like 0.75x50 plus a bit. I think the torque is measured at the crank so if you had a 42T front chainring and 42T rear cog you would have the full 50Nm...

That sounds right to me, the Suntour is 60Nm torque, the Bosch Active Line Plus is 50Nm plus the drive ratio is 42/34 in the easiest gear and with the loss of power through the chain of about 4% that should mean it is about 38Nm torque on your bike so quite a deficit of power compared to the...

There has been lots of problems with Bosch motors and some pretty staggering repair bills for those who had problems and had to pay however compared to the Suntour system which has had the crankset/torque sensor area issues it's hard to say which is worse but certainly as a general rule motor...

I think Voodoo is a US brand but I think Halfords paid a one off fee for exclusive use of the brand in the UK. Some of the models have been similar to the US models but generally they are nothing like them except for the head badge. Some of the Halfords ebikes are coming form the Czech...

I voted Voodoo purely as it has the Shimano motor which should be more reliable. I certainly wouldn't get the last gen Bosch motor that had a lot of problems. Also you are fairly heavy at 18 stone. I seem to remember Cube weight limits are lower than brands like Voodoo. I think Voodoo is up to...

I don't think my suggestion of the Carrera Subway ebike is a bad suggestion. Here is the bike. It's basically a mountain bike but with a rigid chromoly steel fork rather than suspension fork and a geared hub motor using a high quality freehub based drivechain. There was some issues with the...

Thanks for the detailed reply, still impressed with the Yamaha motor from what you have said although being a spinner you give it a slightly easier time. To be honest I've always found Japanese engineering a lot better than German, well in recent years anyway, I used to have a lovely mk1 Golf...

The difference between a freewheel vs freehub is shown in this image. The bearings are wider apart and closer to the dropouts so better supported and the pawl mechanism slightly larger. The freehub is designed for heavier duty use, mountain bikes etc and as a consequence also means a stronger...

I'm quite impressed with your 12,000 miles, have you had any motor issues, what sort of weight are you and do you take the bike off-road much and do any light trails etc, proper rough ground. Also are you a spinner or a masher/grinder. Yamaha make the most reliable motorbikes so I guess no...

That weight limit may include the weight of the bike etc. Sometimes its written as total load which includes all weight and sometimes just rider weight limit. Non adjustable cheap front forks are horrible with heavy riders and are relatively short life for any rider in my experience. As a heavy...

Did you download the manual from the suntour site to see if that helps troubleshoot the problem. I don't think the bikes always come with a printed version...

You could do a visual check of all electrical parts, make sure no cables are damaged or stretched or twisted and all look to be in their proper place. Any expose-able contacts could be cleaned with switch cleaner and a cotton bud. Some people use cable ties and insulating tape to make sure the...

The reason I push the Subway is its an all-round great bike, its great off-road, gravel paths, commuting and capable of taking lots of abuse but its not heavy because it lacks suspension and has 27.5" wheels and the ebike version should be pretty much the same. I think rigid mountain bikes like...

Your comments are coming across as extremely biased and clearly defending your commercial interests. It's easy to claim a bike will take a lot of weight if you offer a short warranty as failing frames will likely be outside the warranty period. I prefer to take the approach if a bike company is...

I don't think rider height has much to do with wheel size, you get children's road bikes that use 700c wheels its all about the frame geometry and how it integrates those wheels into the design. 5'5" isn't that small anyway according to halfords that is the lowest height for a medium 18" size...

I agree with a lot of your points but the Subway does have good tektro hydraulic brakes and more importantly is fully rated for a 120kg rider with a strong mountain bike frame that will have no problem taking 120kg rider weight as will the strong mountain bike wheels. Step thru's often require a...

I think the Subway e-bike is probably about that 20kg possibly a smidgen below. The normal Subway is actually lighter than many 700c hybrid bikes like other Carrera models despite having a mountain bike frame and mountain bike wheels because it lacks front suspension and those can add up to 2kg...

It's a German brand but the company is dutch owned and pretty much all the components come from the far east including the frames and forks. It's more of an assembly plant. If you like German brands then fine but they are nothing special and I've seen better assembled bikes come out of Taiwan. I...

Considering your using the cycle2work scheme I would just go with an e-bike from Halfords to get the maximum discount on your purchase. Something like the Carrera Subway ebike is ideal, simple design that is very versatile. It's basically a rigid mountain bike. Halfords do some brilliant deals...
