The 48V 250W DWG22C is made by Shengyi, the road legal version of their DWG22 made for us, direct replacement for the 48V SWX02 that we sell but with a cassette fitting: http://www.syimotor.com/productDe_3.html The shipment arrives in a few days. I'll post it on the website after checking.

yes, a fair bit. - it's a collection of parts, not a properly worked out kit. Mine is neat and tidy. - his battery is 48V 10AH, mine 48V 12AH, 20% more charge - his kit (500W) is not road legal - he doesn't specify the model and winding code of his motor.

if you intend on spending £1300-£1400, then your range of bikes is considerably enlarged. example: https://www.e-bikesdirect.co.uk/electric-bikes/step-through-frames/wisper-705se-stealth-24-wheel-electric-bike-blue Still, dealers need a minimum of 20% margin to survive. It's a tough life, he...

aluminium suffers from galvanic corrosion in presence of salt in the air. once established, the corrosion spread. The product of aluminium corrosion attacks steel. You have to clean all the parts and oil them.

if that were true, @ 25%: £916-£225 = £687 for the manufactuer. @40%: £916 - £366.40 = £549.60 less import duty, wages, promotional budget, storage, delivery to the dealer, freight, waste disposal, product liability insurance and assembly labour. there is little money left to spend on the bike...

On an £1100 bike? VAT: £183.33, ex VAT: £916 His gross margin is about 25% on £916 = £229. Your credit card costs him 2%, £22. He's spent money on your demo bike and maybe an hour on advising you. Then he'll spend another hour to prep the bike for you. Have pity on him.

true, but the point that was made by a few was that you can still ride home with a hub drive if the chain broke. The other point is compared to unpowered bikes, crank drive inflicts more wear on chain and hub drive less.

have pity on the shop owner! He has rent, rates, wages, insurance ...

there is no need to do anything. Grease may help a bit but can also be washed out. Also, ballbearings should not be overgreased. Most of the cases I have seen are due to riding on the beach and parking the bike where it's rained on. Riding in the rain is not a problem. good bearings are always...

some of my customers report about 15,000 miles with the original set of ballbearings whereas some only clock up 2,000 and need a new set. That shows how much variation there is if parking your bike in the rain or riding on a beach where salt gets inside the motor.

Neither type of motors requires any maintenance unless there is water ingress, then the ballbearings will need replacing. The cost of replacing the ballbearings for a hub motor is about £80 including labour - a bit more for crank drives. The main difference between the two types is the cost of...

I reckon any of us can spot a beautiful woman in any clothing.

I didn't say it's a bad thing, QVC offers similar bikes in the past. However, if you look at value for money, their offers are not outstanding. Most of their bikes are at the very low end of the market: steel frame, small motors, LED panels, low end components like stem, handlebars, saddle post...

a gear shift sensor will help. I prefer my 48V TSDZ2 to the BBSes.

your Ezee kit was precisely the original kit for someone who is 'top heavy'.

I suspect the durress is not so much from members of their family as from tradition and culture. Compare Iranian women for example to Saudi women.

CD motors with torque sensor output is limited to 4 times the input torque, so about 400W-500W, well within the capacity of the chain. That's about par with the Bafang BBS01, but BBS02 and BBS03 output is much higher, 700W-1000W. True. But their equipment is in a different category. Also true...

yes, that will work. The main problem for small riders and big bikes is that the arm reach feels wrong, so the bike appears a bit clumsy. I do agree that 24" bikes will suit you very well but you shouldn't have excluded folding bikes in your search. Some modern folding bikes are much lighter...

the threat that the police are able (if) to verify e-bike speed should be enough to reduce substantially the number of e-bikes fitted with direct drive motors.

I didn't know that BJ has a radical plan to level up the economy. As far as I can see since BJ becomes PM, there is no 'up' sign. consumers' confidence is down, not up. Car factories' output is down, not up. The value of the Pound has not improved. and where would the money come from? Already...
