I fitted the kit without any significant difficulty, but here are some useful notes:
1) some extra washers were needed to get the correct padding for the screws bolted to the flange on one side of the crank housing.
2} the placement of the magnet on the rear wheel spokes for the unit to sense speed was a bit sensitive, but once settled has worked well.
3) There is also quite a bit of spare cable as the kit is obvious;y made to fit a variety of bike frames. I tied these back with a considerable number of extra Tywraps, but if you are not careful it can be a bit of a spagetti junction.
4) I haven’t fitted the brake levers with built-in switch: so far this hasn’t caused any problems as I don’t make a habit of pedalling and braking!
I was not happy that I could mount the relatively heavy 4kg battery securely to the relatively lightweight water-bottle mounts (which were in the wrong place anyway). Hence I invested in “Grin Tecnologies Double Bob Battery Mount” which is a much better solution.
The bike now runs very easily even into the teath of a gale! I hope it will continue to work as well in the years to come!
Very easy to install (and delivery was faster than expected), setup on my MTB worked immediately. First “proper” trial off road on some very hilly terrain and very impressed with the torque control and the response of the system. I’ve only used front hub emotor before and can say this beats it hands down (but no surprise there).
Installed the throttle control, but no longer use it, as the torque controlled application of power is very good. The different torque modes allow you to decide how much help you want but you do have to pedal 🙂
Also got to say that Junstar were brilliant.
Highly recommended
Fatti solo i primi 100 km e per ora funziona bene. Scelto perch ha il sensore di coppia e la pedalata rimane naturale con l’assistenza proporzionale allo sforzo della spinta sui pedali. Montato su una bicicletta pieghevole di Decathlon.
With a 9 speed cassette the gear ratio is too high. It took me way longer to install than I expected. The electrical side of the install is quick and easy but the mechanical side can be tricky, it depends on your frame. I had to debur the bottom bracket mounting and cut away the front derailleur cable guide with my multi-tool. If you don’t have the tools and skills needed, don’t bother. It’s a decent motor but don’t expect it to perform like a Bosch CX gen 4. I wouldn’t bother fitting the brake sensors, who pedals when braking? What the kit does lack, is a gear change cut out. Just go easy on the pedals when changing gear.
Recommend you get a really decent bike to fit it in first fit wasn’t great but put it in another bike and really impressed with performance, also make sure you get good clearance around the motor or torque sensor won’t work. Early days but so far seems great.
I can’t believe I waited so long to fit this to my bike. I had many concerns about spending so much money and then finding problems getting it installed but after watching You Tube videos covering the installation I decided to take the plunge and have no regrets. The motor works perfectly.
Three minor points. 1: I couldn’t fit the connectors for the brake switches into the control unit, so I just left them disconnected. This doesn’t seem to matter: I’m unlikely to pedal and brake at the same time, that would be silly. 2: The magnetic sensor that counts the revolutions of the back wheel is a bit fiddly to set up. If the magnet passes too close to the sensor it goes crazy and senses a speed of 99.9 kph which cuts the motor, so I had to tweak the distance until it registered correctly. 3. I got the rear rack battery, which is simple enough to fit but the heavy battery jumps up and down in its cage whenever you hit a bump. I’ve bodged it by jamming the battery in place with a wooden wedge, I’ll need to find a better solution.
But overall, a well deserved 5 stars from me.
Bought this as a complete kit, mounting not too difficult.
And it works well, has transformed how I cycle and how far I cycle.
I am well over 60 having had two bouts of Covid energy was lacking, this motor is exactly what I needed.
I thought the price of the kit was reasonable, if I had bought individual bits from other suppliers the cost would have been a lot more.
I suffered a broken mounting bracket, I contacted the supplier through Amazon and they replaced it.
If I could have given 4.5 stars instead of 5 I would as the instructions are rubbish, plenty of stuff on You Tube though.
Very well made item, easy enough to fit, delivery time was a week ahead of schedule, no complaints.
Solo le falta quitar el limitador de 25kg. Necesitara informacin para quitar la limitacin. Gracias ya sera perfecto.
Il pacco arrivato poco prima del previsto e questo un ottimo servizio. Il prodotto facile da montare. Divertente da usare.
The conversion was really straight forward to carry out once the old crank was removed, but I had watched plenty of YouTube videos. The only issue was connecting the battery as it had different connector to the motor. Needed to fit 2 bullet connectors. I am really pleased with the finished result. It looks good and the performance is excellent, it enhances the whole bike experience and will encourage me to go biking more often. You still need to put in some effort and use the gears but help is available when needed. Am able to go a lot further and faster and not worry about head winds and hills.
Ya tena montado el motor de 350w 36v y estaba encantado. Montando el de 500w 48v el cambio ha sido enorme. Se nota claramente la mayor potencia, prcticamente me permite de elevar mucho la velocidad media. Tena montado una batera de 36v 12Ah, la he que cambiado con una de 48v 20Ah; prcticamente inagotable, puedo tranquilamente superar los 100km de autonoma. No puedo proporcionar opiniones sobre el cambio del modelo, segn dicen durar ms tiempo… el tiempo lo dir. Me confirmaron que todos los accesorios eran intercambiables y en efecto solo tuve que desmontar uno y montar el otro, as de fcil (mont el antiguo a la bici de mi mujer). Viene limitado a 25k/h pero se puede delimitar y me supera los 40 km/h en llano. El tamao es el mismo y si no fuera por el dibujo diferente en el crter no se distinguen las dos versiones. Contento la primera vez (hace dos aos) y sper contento la segunda.
*updated* it’s on the bike and is superb. Extra weight isn’t that noticeable and the range is much better than old 17.5ah battery. I got the 25ah one. Fits on a voodoo Bantu with extra clips sold separately.
Arrived early, they messaged before despatch to check I had ordered the right things and the battery would fit as I ordered a larger than usual one. Brilliant service. Still to put on the bike, but all boxed as new inside (minor dent on outside of box appears to be standard courier damage, nothing major). Included correct sensors (thanks to the pre check message :)) also included a connection wire for battery. Superb all round.
