Expert Review

Review by: Petra T.
The man who invented this rocks! Whether you want an item of this modification this one IS WINNING!! Trust me, I realize what I’m talking about. I have only had it for a couple of weeks, but I have to come on here to spread the good news: Bafang BBS02B 48V 750W Mid Drive Motor E-bike Conversion Kits BB 68-73 mm Electric Bicycle 8FUN Powerful Engine 44T 46T 48T 52T is absolutely what is pointed. The cost was profitable and shipping and service was perfect.

Honestly, I had a severe way to such a rate of buyer’s contentment. Have had a bunch of unsuccessful bargains. Because of these accidents, I comprehended that all of these were just vain expenses. Nothing but anger and disappointment. But I made a decision to give it one more chance, so I did my search. I elaborately examined many stores and many of alike articles. I viewed a lot of manufacturers’ characteristics and references. Then I came upon this site and Bafang BBS02B 48V 750W Mid Drive Motor E-bike Conversion Kits BB 68-73 mm Electric Bicycle 8FUN Powerful Engine 44T 46T 48T 52T – and made a decision to give this another chance... and I'm so satisfied I did.

I took up it based on the rave reports and excellent value. For this money, I am very delighted. I am pleased by this product! It’s one of the best I have ever took up, no sorrow at all. This fits my wishes better than any of the other articles that I have tried. I can't believe I didn't get this before.

If you have need for an article like this, this is an exclusive variant. 5* all the way. I'm really satisfied about it – I’m even going to buy more when they are on sale. This article is really one of those details that make monotony nicer. It more than meets all the criteria that are vital for me. Good conception – winning item overall.

OK, I'll quit rambling, but I just had to give this winning item a small positive review. I highly recommend!

    Excellent quality products from this seller highly recommend

    Verified buyer

    The whole set is good. In youtube found how to program the display. Wheel size, degree of help, maximum speed. On a flat without pedals about 50 maximum on 26 wheels. Weight 70. A good mountain without pedals will not come. We need 1000 watts already.

    Verified buyer

    Kit arrived in perfect condition, free blisteringly fast. Flawless Operation

    Verified buyer

    Great conversion kit. Only a special key is not included, but I already had one from the previous set. The headlight surprised me, it shines very well.

    Verified buyer

    Fast. Small error on the choice of the display... I had to do with it so as not to waste time.

    Verified buyer

    Top very fast Shipping Goods top thank you.

    Verified buyer

    It´s a great motor and the kit is easy to install and everything is great quality. My only complaint is that it doesn´t draw power as smoothly as the BBSHD and sometimes cuts in when it shouldn´t.

    Verified buyer

    Verified buyer

    Blows a fool even with half-dead batteries from the remnants.

    Verified buyer

    Motors are good on 26 wheels 45 km. h gives (perhaps there would be more than 45 costs in the computer), with the installation on the male frame there are no problems, and my wife had to be wise with the transfer of the cable of the rear speeds (the cable went under the carriage and with the motor climbs only naked) wires going on the lantern from the motor of incomprehensible colors and inserted quite tight, When the polarity is confused, the lantern does not work and the wires are not convenient to disconnect, in general the motors are excellent tests 4 day riding in the mountain area turned into fun. Delivery 40 days packaging is good, worried that they can take for customs clearance, but everything is ok. Thanks to seller and manufacturer. I would like a description in the kit and utilities for programming for this money can be put in the box disk.

    Verified buyer

    Before peter 25 days, the track is not tracked, brought the courier. The motor is just super, made a month before sending. As a gift there was a headlight, cool, ordered already for money the second one is the same for another great. Seller recommend!

    Verified buyer

    Product arrived within not tested more arrived well packaged very responsible I recommend

    Verified buyer

    I highly recommend this seller and this motor. The experience of using is very positive, the bike is reborn! With the motor, i advise you to immediately take a gear shift sensor (that would not tear the chain) and a usb programmer. The seller asked instead of the headlamp to put the key for screwing the carriage. I put everything myself in 3 hours. The purchase exceeded all my expectations!

    Verified buyer

    Fast shipping, mounted and working perfect, good seller

    Verified buyer

    Could not be any happier with my purchase! Already 740 km on the motor and have not had any issues yet! an A+ rating for the seller! Always fast to response and address your concern and issues! I would def recommend this seller to anyone considering getting a Bafang kit! You won't regret it. Oh almost forgot, VERY FAST shipping. I have installed a 17.5 Ah 48v battery and I can get around 50 KM range on a moderate use! Buy of this seller, thank me later.

    Verified buyer

    Did very well. Answer questions so fast.
