At the time I bought the Q128H kit, the KT was just speed controller. Their torque simulation was sold as a separate proiduct with an 'S' suffix. Note: The word 'speed control' is not used by Lishui. They just say their controller is programmed with their algorithm that they have refined with...

Are you using their current control controller? I rode the Q188H that I bought from bmsbattery for about a month. Q128H 36V800W Rear Driving EBike Hub Motor RPM 201 Voltage 48V (bmsbattery.com) It came with KT 20A 6-FET speed controller and KT LCD3. At the end of the trial, I decided to buy...

I always stick with 'A' cells from Panasonic or Samsung. I don't make a big deal out of it because the reason is self preservation. If you google CCJ against the two companies I work for since 1981, Solidisk and Woosh Bikes, you won't find any because I wouldn't knowingly take any unnecessary...

I agree. None of the long standing OEMs would shout out from the rooftop that they only use 'A' cells but you would assume that they do, it's just common sense because they have to cover product liability. There is no point to take a chance with second best.

I am always a little irritated whenever someone says 'KT controller is miles ahead' or some such statements. I have bought KT controllers for testing and as far as I can see, Lishui controllers are a more sensible choice. I will of course justify why not just me, but the majority of OEMs buy...

40 mile ride is physically testing on a full sized bike, more so on a small wheeled bike. The good thing about the Rambletta battery is it pops out of the frame as soon as you turn the key 60 degrees, it is at easy reach, you do not have to bend down to remove it or fiddle with battery rails...

We all instinctively agree that cells with hidden defects should not not be sold but there is no visible sign to distinguish those cells from the rest other than the wrapping and you have to trust the honesty of those involved in the manufacturing and distribution. I sometime compare that with...

Cells that are not 100% are likely to have hidden manufacturing defects. we should all prioritise avoidance of risks.

Grade A cells are guaranteed to meet or exceed manufacturers discharge capacity (100% ) and performance, with no visual imperfections. Grade B cells have 90%-95% capacity. Ungraded cells have typically 90% or less discharge capacity. The main issue is hidden defects. There is no simple way to...

e-bike batteries are a lot safer now than 10+ years ago. They are built with cylindrical cells rather than pouch cells. Cylindrical cells have anti-explosion caps, so they don't generally explode unless you have a very big capacity like 1000+WH where the heat generated is so overwhelming that...

If the OP weighs only 70kgs, then the Rambletta would suit.

How old is your kit? If it's not the B version, It's likely the blue gear that's slipping under load. Tongsheng redesigned it's motor, the newer B version, replacing the blue gear with a new clutch under the main gear. Check the label under the motor. Google tsdz2 blue gear for more info.

why do you think that?

hub gear on folding bikes gives perfect chainline, avoids problems with damage to the derailleur, a common issue with folding bikes. Brompton bikes for example wouldn't work without a hub gear.

We have always had product liability insurance since 2011, so the answer is none.

I rode the Zephyr CDN for a year. Absolutely loved it because it has hub gear, small wheels, throttle, climbs any hill and a piece of cake to carry in cars etc. However, the CD motor added about £120 to the price. People prefer the cheaper Zephyr with Bafang rear hub motor, still climb any hill...

Just once but once is enough. The bike was bought in 2013. That bike had Chinese pouch cells. The lady left her bike at her dad's house. Smoke came out of the battery one afternoon when nobody was around. That cost my insurers some £33,000 4 years ago. I am mainly against advising members to...

I have done that some 10 years back. This is the Woosh Zephyr CDN, sold for £749 in 2014. Folding bike - Kudos Secret vs Woosh Zephyr CD vs Other? | Pedelecs - Electric Bike Community There is no real need for a CD motor on folding bikes, most people see folding bikes as a low cost option...

I made the Rambla for that and the problem was Mid drives appeal more to those who like demanding rides, the Rambla is unsuited for trail riding.The frame flexes a little and that worried me. I will be replacing the rear hub motor on the Gran Camino with the Ananda mid motor as soon as the...

I am looking for a new frame.
