The downtube battery is part of a Bafang 48V 750W (BBS02B) Mid-Drive Conversion Kit.
The terrain I ride of is undulating through rainforest on the Evelyn Tableland Nth Qld. Twenty klm rides @ ~ 30klms/hr reduce charge to ~ 70% which works for me.
Mated to the mid drive motor with efficient use of gear changes this is a beaut match for my needs. Keep the use of gears somewhere in the mid range for this motor and the battery will love you for it.

Been shopping with Pirez for a while now staff are very helpful and friendly. Products are top quality and great delivery too

Awesome tool

Came on time and is working well

HD Freewheel Clutch

Absolutely stoked with the unit. Easy install and compatible with what parts I already had installed.

Delivers a much smoother torque curve than my previous 750w motor, putting less strain on my other drive train components on take off/lower gears (winning).

A lot better usable power in the mid to high range RPM, excellent for the hill climbs.

Also the customer service was on point, they answered all my questions in regards to the upgrade. Will shop again

Exactly what I was after, delivered quickly

After doing quite a bit of research and seeing Pirez being recommended in a few places for ebike conversions/sales, I was glad I made the choice to proceed with them.

The Scene 2 with conversion (750W Bafang) that arrived was in perfect condition, required basic bike know how to assemble (shipped interstate), and was ready to ride in no time. After putting 150km on the bike I can attest to it being a great cruiser both on the road and on bike paths, especially with the addition of the comfort seat with shock absorber. I've since added a rear rack and compact bag for shopping and commuting, something I think is probably a missed opportunity on the websites ordering options as it's a no brainer for this bike!

My only disappointment is that Pirez aren't in Queensland for when it needs it's first service!

We have a Trike and in our recent move safely put the battery charger aside so that it wouldn’t be lost.

Of course, it was!!

A quick phone call and the new cable was with us in a week.

Just in case, we enquired with our NDIS provider. Their price was an extra $50, and had to be ordered in.

Thank you Pirez!!

Ps The original lead turned up so we have two. We don’t mind having the two!!

Thank you for prompt delivery of a hard to find charger.

Recently purchased the 500w 36v Bafang mid drive. Easy to install and plenty of power for what I use it for. Still haven’t tested the battery range, but I’m sure it will get me to my destination and back with no worries. This kit was fitted to my FUJI Nevada 29er with hydraulic brakes and a ten speed rear cassette. The motor moves my 100kg around with no worries at all. Thank you Pirez for supplying everything needed to get me going.

Good value.

Purchased to replace the one that came with a kit that had failed - kept getting error 21 - and while this is showing signs that its working correctly it did not fix the problem in my case (I suspect corrosion and/or a damaged wire somewhere in my setup).

An easy to install replacement motor with plenty of hill climbing ability, very responsive motor.

Easy to install and a great little motor with ample torque. The 36 volt 24ah battery is more than enough for this 500w mid drive motor and moves my 29er mountain bike and my 100kg with ease. Even though there was supply issues regarding some key components and a longer than expected wait time for my order to be filled, I’m very happy with this purchase and the ability to communicate with the staff either by phone or email to help put any concerns at ease. I would use Pirez again as they did come through in the end and were very helpful and polite.
