@mathewslack I think it is very hard to gain an accurate picture of reliability based on what is on the web. I suspect that it depends on how the motor and battery have been used. Many mid drives are fitted to mountain bikes which are likely to have a hard life especially if they get washed...

@Mathewslack - thats a great idea. I asked because ICE, who make my trike, now fit the Shimano motor to their new electric trikes. This means that a custom Shimano friendly front boom should be available. https://www.icetrikes.co/ . Also I suspect that the Q factor is much narrower than my...

@mathewslack I was not aware that it was possible to buy a Shimano system, may I ask where you purchased it? S

@Bikes4two Thanks for the picture and measurements. So it seems that fitting a single Bafang crank will reduce the Q and crank Q by 17mm and reduce the misalignment by the same amount. I'm going to continue with the non electric version and conduct some more longer rides so that I have a...

Numbers numbers numbers! I have just re-measured both the original cranks and chainwheel set, which are presently fitted to my ICE trike, and the TSDZ2 which was measured unfitted and compared with a design drawing I found on the web. Accurate measurements are quite difficult so I have to say...

I will try and find the figures and post them. I am aware that I am blaming the TSDZ2 but the other factor is that I was riding further and often above the motor cutout speed. So my plan was to ride the original unassisted version over similar distances (forty five miles) to see if my knee...

Here is a link to the volt meter I used : https://www.amazon.co.uk/dp/B09XTMJTHW?ref=ppx_pop_dt_b_product_details&th=1 I re-purposed a nylon tube clamp originally used to fit a bicycle light to mount the meter. I also "gobbed" up any slots in the back plate with silicon to waterproof the...

Thanks for your comments. You are all correct I had not appreciated that the motor chain wheel does not trigger the torque sensor and having looked at the trike I don't think there is enough room especially if I wish to retain the water bottle. I will probably be better served just to buy a...

I have a Tongsheng middrive motor that I have had to remove from my recumbent trike owing to problems with my knees which I attribute to the wider spacing of the pedals and the offset cranks. I am considering trying to mount the motor on a custom, yet to be built, mounting plate which will be...

Hi, I installed the 48v version to my ICE recumbent trike. The kit was supplied by Woosh and was straight forward to install although I needed to source a longer cable for the rear wheel sensor. The kit came with a large 720Wh battery and I could achieve high milage per charge riding in flat...

Quite a difference in price though : From a UK site picked by Google, i.e. I have not used it so info only. https://simplybearings.co.uk/shop/advanced_search_result.php?search_in_description=1&keywords=69022RS&

Yes, I believe that the lithium is capable of eating through aluminium even if it does not catch fire.

Depends on how you define massive. My trike has 20 inch wheels all fitted with Big Apple tyres i.e. large balloon tyres. Initially the TSDZ2 was over reading by approximately 10% when compared with both my Garmin GPS and Sigma cycle computer. I played with the diameter setting and if I...

*SJPT - no idea why the reported Ah is less than the constant current multiplied by the time. Possibly because its a cheap uncalibrated watt meter. I have confirmed what the units are suppose to display " The displayed value is the total charge in Amp-hours (x1000=mAh) delivered since the...

Trust me thats a lot of miles! All the points in your post are excellent - thanks. You are correct about the Grin charger being expensive but I do have several e-bikes in my household so it may be of value to me as it would simplify the charging equipment and possibly be more accurate than my...

I am concerned that the 4wh per mile seems low as I do not class myself as a powerful cyclist. As the weather improves I will be using the e-trike more so will collect more data which I'm happy to report. I will try and collect more data points to enable the plotting of voltage to Wh used. My...

The Watt meter is fitted to the charger and I have recharged my battery to full as indicated by the LED turning green on the charger. To recap following my first charge I rode 76 flat Lincolnshire miles mostly on road and was wondering why the battery display was still showing five and half...

Great post. Your use of a voltmeter appears to be the only meaningful way to assess the charge status of the battery i.e. measuring the floating off load value. On load voltages will be all over the place depending on the load. I will be searching my parts bin for some connectors to add my...

Crikey now I feel guilty it seems I've opened a Pandora's box . All I meant to do was express my surprise at how the display of battery state did not appear to be reacting to the use of assistance. If you do take a closer look I would be interested in how the four LEDs on the battery work...

So how does the six segment display of voltage operate on your rides? Does the rate of change of the display accelerate as the number of segments decrease and is there any correlation with what you see on your watt meter? S
