Electric Bike design, sales and repair
Hi, my name is Ants and I have been doing electric bike design, sales and repairs in Christchurch, New Zealand for the past 10 years.
I love constructing custom e-bikes specific to customers individual requirements. I make and sell all types of e-bikes, from quality commuting bikes to high spec, performance off road machines.
Off road e-bike hire / electric bike rental for rail trails is available for periods of one week or longer - ideal for campervan holidays enjoying New Zealands rail trails and off road tracks.
I fix all types of e-bikes and their batteries -> all makes, all models.
Please scroll down for more details about e bike servicing and repairs.
In order to give you the most choice and best value, I don't tie myself to one brand or one franchise of ebikes. I stock the German designed Magnum Ui5 and order and sell from a wide range of other types depending on what the customer wants :)
See the Magnum range and other ebikes available from me at:
My goal is to get people out of cars and onto bikes !
Contact me to arrange a test ride.
The Magnum Ui5, Electric Bike Report gave this bike a 9/10, calling it "a beautifully designed, purpose built, affordable electric bike well suited to urban riding or commuting".
The sleek 13ah Samsung battery, powerful rear-hub motor, easy step-through frame and the comfortable riding position make this bike fantastic value at $2,499
This is the Raptor
, a beautiful and very capable off road BEAST :)
I have a Raptor and a Forza LTS (step through) available for hire. Both are tough and dependable, have the powerful, geared, Ezee motor and hydraulic disk brakes front and rear. They are suitable for rail trails and off road use, these off road electric bikes are a great way to see more of New Zealand when on a camper van / RV holiday in New Zealand.
If you love e-bikes and are coming to NZ on holiday, you can pick them up in Christchurch. Drive and ride around NZ and then drop them off before you fly out of Christchurch again :)
Located near the Airport, I hire these off road e-bikes bikes out for a minumim of one week. For more details about off road and rail trail e bike rental, send me an email.
Electric bike servicing:
If you need your e bike serviced or repaired, get in touch. I service all makes models.
I have been trained by Gazelle in the Netherlands to service their e-bikes.
As far as I know no one is selling or servicing these e-bikes anymore in NZ, but there are a few hundred of them out there. If you have an electric Gazelle that needs repairs / servicing, please send me an email (my details are on the contact page.)
Repairing electric bike batteries
has become a speciality for me.
I have built up a set of tools and equipment that allow me to charge, load test and discharge whilst measuring the coulomb's flowing in or out. Either of a single cell or of an entire battery pack.
This combined with an in depth knowledge of the batteries and their BMS circuitry allows me to be able to resuscitate a battery pack that has been deeply discharged.
What do I mean by deeply discharged ?
This is often when a battery has been left for a long time (say 6 months) and now refuses to charge.
I also repair BMS circuitry, and chargers.
This bike was an e-bike conversion for a customer who wanted assistance climbing the final hill of a 35km commute. It had a 36v 14Ahr Lithium battery pack and an Ezee 300w geared hub motor to allow it to eat hills for breakfast.
The internal 5:1 planetary gears inside the hubmotor allow the electric motor to spin fast and produce good power, even when the wheels are rotating slowly as happens when riding up a steep hill.
A lot of electric bike motors are direct drive, and struggle to climb hills.
Here is a photo of a 50yr old, climbing Baldwin St in Dunedin (the steepest residential street in the world
on an Ezee bike.
He climbed it three times that day - thanks to the powerful hill climbing assistance of the Ezee hub motors.
Here is a link to the newspaper article.
