I had a similar problem caused by the dirt in the pedal assist sensor causing the magnet disk to seize and slip on the crank.

I I am just wondering Andy have you taken into account the extra height that will be added to the front of your bike ( and bottom bracket) due to the extra fork length (2 inches or more depending on travel) ?

You can sometimes get the best of both worlds by fitting a large front wheel and a smaller rear wheel. I always liked the more 'relaxed' or 'comfort' geometry that results from this.(Front higher, easier to put your feet on the ground, more stable etc). I am riding at the moment a Carrera...

I live close to an mtb trail center and the Bosch motor mtb are popular and are good climbers. I often wondered is it that the motors are good or is it that the gearing is good or perhaps both. These bikes have small front chainrings of 34T and large 51T on the back which would give about 50%...

Another thing to bear in mind is that the torque quoted for mid drive motors is often at the chainring whereas hub motors are quoted at the wheel. With a middrive you have to adjust the figure by the ratio of the largest working rear sprocket to the motor chainring and allow a few %.chain...

I think Halfords guarantee the battery for 2 years/500 full cycles so I think I would go back to the shop if its not a simple fix.

I think there is a safety feature with most controllers that register an error when you power up with the throttle pressed or the wrong throttle signal voltage as would be your case. You could try powering up the controller first and perhaps then connecting the resistors although I think you...

I have a MXUS xf07 which may be different to your Bafang version which I never knew existed. Mine were 6001RS and 6902 RS (cable side) I think but you should check as suggested above . I got mine at the local motor factors. They were made by 'Codex' and cost me 10 euro each.

Your not on your own. My old Nokia flip phone that I had for over 10 years broke down last year and replaced it with a Doro G2 flip (dumb)phone. Small and compact with large text and only needs charging every week or so. It is possible to live without a smart phone.

You are switching back and forward between a 36v and a 48v battery so I think perhaps your controller (or LCD?) gets confused.!!!

If If I may add one thing extra to your list, one thing I have come across twice lately is a problem with the 'rubber boots' stopping the brakes when the pads are worn down a bit.. The boots were made from a very hard pvc type material rather than the normal flexible rubber . In both cases, I...

The LCD3 sits about an inch high on a pedestal. I took the display off the pedestal (2 screws) and fitted it lower, sitting directly on the handlebars using a bit of steel holed tape and cable ties. Its much more tidy and less likely to get damaged, especially when inverting bike for puncture...

Looking at photos above, I think thats a narrow wide chainring. Every second tooth is narrow/wide and the wider outer chain link must go on to the wide tooth and the inner narrow chain link to the narrow tooth.. https://www.firstcomponents.com/narrow-wide-chainring/

What would you recommend to lubricate the roller clutch?. Grease can dry out and get sticky. There has been reports of roller clutches in some middrives slipping after over greasing. I have seen freewheels sticking from grease drying out. I suppose a second question is does anyone check the...

Is it necessary to re-lube a motor? The reason I ask is because my Yose motor have clocked up high milage (20K miles plus) without ever been opened. I have had to open another high mileage motor to replace of a noisy bearing and added a small amount of silicon grease when reassembling in this...

But what I am thinking is that if a retailer/supplier sells a bike or kit and claims that it complies with EN15194, then he has to make some effort to make it tamper proof so to speak. I notice some suppliers (e.g pswpower) sell some kits that are completely open but they do not claim that they...

I am just wondering is it not the case now that all ebikes/kits that comply with EN15194 are suppose to have their parameters locked or am I missing something?

Just to add to Az above, as well as buying the 8 pin controller, I think you may need to buy the 8 wire version of the Vlcd5 as well as special throttle that plugs in. https://www.pswpower.com/products/vlcd5-display-for-tsdz2-electric-bicycle-central-mid-motor-...

Had this problem with my daughters Pendleton back in 2018 ( DNP epoch 8 speed freewheel). Gave it a few squirts of 3 in 1 oil and never had problems since.

What sort of thermal device was fitted to your battery? The reason I ask is because I repaired a joycube/phylion battery lately. It had two thermistors embedded into the cells with white thermal goo and also a thermal fuse on the charging circuit also similarly embedded. I cant see any detail...
