Cycle rack is the one that clamps on the door edges but also bolted into the doors.
Ah, that may be the secret often they don't like to bolt/screw into the doors at all. Carrying that sort of weight on the rack though is still not something I'd do but if you're happy with it then carry on chuck! :)

Would think something labelled at 35 kg the safety margin would be much higher than 5 kg,,BUSBY.

I would never assume anything ... especially if doing so could cause issues further down the line ... there have been reports of doors being 'distorted/damaged' due to the weight they've carried.

Like every good pupil, it’s best to do your homework. I’ve emailed Knaus about the bike carrier and weight of ebikes I’m considering, to see if the back wall of my coach built can safely take the 40kg weight. It’s been two weeks now and all I’ve had is an email to say that they’re considering it.

In a word ..... YES (y) (y)
THIS ☝🏼
Convert your already purchased "owes you nothing" bikes to electric assist with a crank drive unit and a battery in a bag for the a frame.
Cheaper, easier and no love lost if you don't get on with them. Can always resell the built bikes on ebay for more than the kit cost you if you wanted a "get out of jail free card"

Apart from the physical weight of the motor and battery combo, I don't know why Ebikes are so heavy ? Our Kalkhofs are not light by any means, my old Marin hybrid is as light as a light thing and could easily handle the 250w output of an ebike motor. On the whole though, the ebikes have been a Godsend with my dodgy lung and Val's knackered knees and I would recommend them to anyone with fitness/medical issues.
I rebuilt a bike using a Giant alloy frame & the usual transmission & wheels. After a couple of years I converted it to an E bike. The weight has increased by an amount that exactly corresponds to the additional weght of the battery, controller, and motor. A lot of E bikes appear to be built on heavy frames with cheap running gear and controls that no doubt add considerably to the weight. A really excellent E bike can, IMO, be built by selecting a non-electric bike of the quality you desire and then adding a motor kit. That way you have control over the quality and weight of all parts used.

What kit did you use?
Tempted to convert our Specialized bikes & flog the e-bikes.
Hi Lenny HB , I used the tongsheng tsdz2 kit it uses a torque sensor so the harder you pedal the more assist you get plenty of info if you google it I got the 48v kit and a 20ah battery the whole kit came in at about £600 then about 2hrs to fit

Interesting post. If I had lightweight specialised bikes like Lenny HB it would be tempting. But having bog standard Giants that are already quite heavy, this would really add to the overall weight I think.

Have you upgraded the braking system?

The good thing with torque sensing motor is it only kicks in when you apply pressure to the pedals (wont while standing still), no need to uprate brakes as soon as you stop pedalling so does the assist as for the weight the motor is really quite small maybe a couple of kgs its the battery that adds the weight, we bought 20ah batteries but on second thoughts I wish I had of bought something smaller it seems to last forever.

Is it rude to ask how much the conversion cost Neil and is it an easy job? BUSBY.
The conversion kit was £176 and the battery was £179. All took a couple of hours on my bike, less on my wife's as I knew what I was doing.
As long as you can replace the rear wheel and plug wires together then the job is easy.....

Unless you’re used to working on bikes and got all the right tools to remove the crank etc a hub conversion is probably the easiest for a first timer. And a front wheel, easier than a back. :D2

Mrs Whack had amongst her bike collection a good cyclocross bike. Incidentally we find cyclocross bikes or the new fangled "gravel" bikes the best compromise for the motorhome, capable speed on road and fine for forest tracks etc.

After a couple of years out due to illness we looked at buying an electric bike to ease the return. Now for me the entry point for a reasonable non-electric bike is a £800 - £1,000 anything less and you are just putting off buying a lot of new parts you will be replacing IF you intend to do any sort of mileage.

So looking at electric bikes you had the sub £1,500 heavy and probably limited life battery type - both range and chargers - which to my mind are built on a £450 base bike when you look at the components. Next up were the £1,000 "base vehicle" with a £2 -2,500 bespoke electric kit = £3,000 - £3,500 RRP.

As a "tight fisted northern git" this got me looking at kits - and here there was a similar range! I spent a lot of time trawling the internet and found this site particularly good Pedelecs Forum
I saw no point in taking a good bike and weighing it down with heavy batteries and drive and after looking at what's available I spent £1,100 on a Cytronex . Now that may seem a lot but as I look at it she's got a £2,500 electric bike. Yes there are cheaper kits available but there is a reason they are cheaper.

Sorry forgot to get back to you, thanks for the info they look really interesting.
I like that you can get double front chainwheels so could keep your original gearing, could be useful if you need to get home on a flat battery. Also could save a £100 and a bit of weight by having the 300 watt battery.
With our 400 watt Bosch batteries never come anywhere near to flattening them on a single ride.

Lenny I know you like tinkering with things this is a thread running with a few guys developing new firmware for the TSDZ2 motors good read and very interesting what they are doing take a look
