If the user can remove his motor to send to PCG then the thief can do just the same. Nobody seems to lock their motor.

He would need the 500 pack to match the Wisper, £2099, and pedaling would be a bit harder too because of the range of assist, only up to 3x. The Wisper can be switched to rotation sensor mode, basically going uphill without much pedalling...

what happens if the customer has his motor nicked?

I noticed the range of support 120% to 300% of user input. That means the user has to put in between 45% and 75% of the required energy. Imagine climbing up some steep hills. No wonder Bosch bikes keep you fit and Chinese bikes make you lazy.

Yes, you are correct. The derailleur is Acera M360 (RD-M360GSD), shifter is also Acera M360. The freewheel is DNP 8-speed 11T-34T, the crankset is Ounce GXP 245A-TT, chain is KMC X8.

the bike technician might if he gets the chain length wrong.

no, it's a DNP 8-speed freewheel with similar arrangement (11T-32T) as a freehub. The reason to have a freehub instead of freewheel is because Shimano freewheels have typically 14T-34T while freehubs can have 11T on the smallest sprocket, giving you more gear inches. DNP freewheels have the...

he might succeed soon. I watched Susanna Reed interviewing him - I could not believe the drivel he came out with. Some time ago, I used to find him entertaining but not anymore.

The probability that a cassette mechanism fails on a hub motor is very small but not nil. If and when the freewheel fails (about the same probability that a cassette fails), it is inexpensive to replace. I am always influenced by probability. So given the choice, I'd rather fit a freewheel.

the Kudos Sprint is easy to carry. Its battery is easy to take out, same as the Woosh Karoo. https://www.kudoscycles.com/product_info.php?cPath=1&products_id=349

yes.

the Kudos battery has done 4,000 miles - not bad for a 10AH battery. A new battery made with quality cylindrical cells should last more than that but I reckon not four times more.

Hello ML, I don't think there is. The lightest full size bike weighs about 10kgs unless you want to pay £,£££. If you carry the battery separately, you may find something with a motor weighing in the region of 12kgs-13kgs. It's still heavy. The lightest full size bike I sell is the Karoo...

It goes to show that the tories deserve to be called the nasty party. I think Corbyn needs more personal attacks of this kind. The more Boris tries to caricature Corbyn, the more it shows that the tories have no new policies.

it easy to agree with your view, Danidl. There are few motor options for middle of the road bikes. Here, the Bosch CX reigns supreme. But if you look at cost per mile for these bikes, am I right to assume that most users trade up their bikes within 1000 to 2,000 miles? that will push the price...

Yes, a thumb throttle costs £5.

I am pleased to see R&M choosing the Suntour Aion LO-R for front suspension fork. A vote of confidence like this from R&M engineers is a godsend gift for Suntour. I will certainly try to put this fork in my next touring bike.

I sell direct, Kudos and Oxygen sell through a large network of dealers. Their dealers have to add 30% to their cost price to be able to afford local demonstration, prepping the bikes and looking after you locally. If the Rio is sold through the shops, the shop price would be £1,399, not £1,049...

This may not be an advantage though. If the ratchet mechanism fails, it's easy to replace a freewheel. On a motor with cassette, you will need to return motor wheel. You also don't need as many gears on a geared hub bike. Even if you do, DNP sell inexpensive 9-speed and 10-speed freewheels.

yes, you can fit any front shimano hydraulic brakes but beware, the brake levers look different. Otherwise, it's a 20 minute job. Just loosen the M5 allen bolts, remove the old caliper and the brake lever, bolt the new brake in. The Karoo's Avid brakes have good stopping power because their pads...
